Description
- The disclosures made herein relate generally to exercise apparatuses and, more particularly, to apparatuses configured for exercising abdominal muscles.
- A person's abdominal muscles, which are referred to generally as ‘abs’, comprise a plurality of different muscle. A person's rectus abdominus muscle is disposed centrally along the length of the front of their abdomen and attaches between the lower rib cage and the front of the pelvic girdle. A person's internal and external oblique muscles are disposed medially and laterally, respectively, between the lower rib cage and the front of the pelvic girdle. Accordingly, the rectus abdominus muscle defines an anterior muscular wall of the abdomen and oblique muscles define lateral muscular walls of the abdomen.
- As is well known, preferred approaches for exercising the abdominal muscles provide a safe and effective means for training both strength and endurance of the abdominal musculature. Such preferred approaches provide for incrementally progressive resistance means that prevent the abdominal muscles from accommodating to a specific force while enabling the user to remain challenged in training his or her abdominal strength and endurance as his or her strength and endurance increases.
- Conventional approaches for exercising abdominal muscles without exercise apparatuses are known. To exercise the upper portion of the rectus abdominus muscle in such a manner (i.e., without an exercise apparatus), repetitions of a supine “crunch” exercise are performed in which the trunk of the human body is raised, in a curling motion, with the hips and knees bent and the feet remaining stationary on the floor. To exercise the lower portion of the rectus abdominus muscle in such a manner, repetitions of a supine “knee-up” exercise are performed in which the feet are lifted off the floor and the knees are lifted, in an arcing motion, toward the chest wall. Simultaneous exercising of the upper and lower rectus abdominus muscle is performed in such a manner using a “compound crunch” exercise wherein the supine crunch exercise and the supine knee-up exercise are combined in a coordinated movement. The left internal oblique and right external oblique muscles are exercised simultaneously in such a manner by performing repetitions of the supine crunch exercise in combination with twisting of the torso to the right side and by twisting to the left side to simultaneously exercise the right internal oblique and left external oblique muscles.
- The abdominal muscle exercises described above (i.e., without the aid of an exercise apparatus) are not without hazard and inconvenience, especially with respect to the novice exerciser. One adverse issue associated with such abdominal muscle exercises is that muscle and joint injuries that occur are mostly related to the inertial strain developed when commencing the lifting of the user's body. Such injuries can be especially problematic if the user holds his or her breath while exerting, thus risking injury to the lower back and neck regions of the spine as well as the hip flexor muscles. Another adverse issue associated with such abdominal muscle exercises is that they often inherently cause the exerciser to create an undesirable whip lashing motion of the spine to assist in the initial lifting phase of the exercise. Still another adverse issue associated with such abdominal muscle exercises is that most exercisers find these conventional exercises uncomfortable to perform. Thus, exerciser compliance has been historically poor with such exercises rarely yielding desirable results. This is especially unfortunate for back and neck pain sufferers, because these individuals are often prescribed conventional abdominal muscle exercises to assist in alleviating spinal pain through development of a stronger and more physically fit abdomen. Besides the aforementioned adverse issues associated with such abdominal muscle exercises, spine pain sufferers often have great difficulty in or are precluded from lying on the floor and then standing back up.
- Various resistance-type exercise apparatuses for exercising abdominal muscles are known (i.e., conventional abdominal muscle exercise devices). Such conventional abdominal muscle exercise apparatuses are also known to have limitations that adversely affect their effectiveness, desirability and/or practicality. Many of these conventional abdominal muscle exercise apparatuses have largely failed to provide adequate comfort, convenience, safety, and time-savings while providing endurance training and/or strength training in a manner adequate and specific to a user's individual needs. Some of these conventional abdominal muscle exercise apparatuses provide an excess of resistance so as to allow only a few repetitions to be performed before fatigue sets in, thus limiting the endurance training of the abdominal muscles while increasing potential risk of injury. Others provide too small a resistance such that the abdominal muscles are not adequately stressed so as to provide adequate strength training. Furthermore, such conventional abdominal muscle exercise apparatuses frequently provide only specific exercises thus requiring more than one device to effectively exercise the entire abdominal musculature or require numerous exercise movements, which are both time-consuming and complex to perform.
- Conventional abdominal muscle exercise apparatuses that constrain a person to execute what are largely linear vertical motions and/or other motions that deviate in some respects from the natural, complex curvature motions of the spine during bending, thus presenting a particularly undesirable set of adverse issues. In executing abdominal muscle exercises with such conventional exercise apparatuses, the associated body motion results in bending of the torso at least at some points within the full range of motion that occurs at the hips rather than at the lower spine and stomach, thereby predominantly stressing the hip joint flexor muscles rather than the abdominal muscles in these ranges. Such motions are in sharp contrast to the “crunch” motion, “knee-up” motion, “compound crunch” motion and/or “torso twisting” motion in which the spine is desirably flexed forward in a curling path. Thus, the abdominal muscles consequently do not receive optimum benefit from use of such conventional exercise apparatuses.
- Disclosed in U.S. Pat. Nos. 5,071,119; 5,069,448; 5,046,726 and 4,863,162 are examples of such conventional abdominal muscle exercise apparatuses that constrain a person to execute what are largely linear vertical motions and/or other motions that deviate in some respects from the natural, complex curvature motions of the spine during bending. The abdominal muscle exercise apparatuses disclosed in these patents address individual problems associated with performance of crunch motion exercises. However, as discussed above, there are numerous problems that exist in conjunction with the means in which such conventional abdominal muscle exercise apparatuses facilitate such crunch motion exercises and that limit the effectiveness in which strength and endurance training of abdominal muscles can be safely performed using such conventional abdominal muscle exercise apparatuses.
- Therefore, an abdominal muscle exercise apparatus and associated exercise technique that overcome limitations and drawbacks associated with conventional abdominal muscle exercise apparatuses and associated exercise techniques would be useful and novel.
- Abdominal muscle exercise apparatuses and associated exercise techniques in accordance with embodiments of the inventive disclosures made herein overcomes inadequacies of conventional abdominal muscle exercising apparatuses and associated exercise techniques. Specifically, abdominal muscle exercise apparatuses in accordance with embodiments of the inventive disclosures made herein provide an adjustable, light-weight, compact and easy to use strength and endurance training apparatus configured for exercising the abdominal muscles in a time and motion efficient manner. Such abdominal muscle exercise apparatuses enables a user to easily assume and maintain a individual biased anatomically correct crunch motion, while minimizing the risk of injury associated with exercising abdominal muscles. Through the use of an exercise apparatus in accordance with embodiments of the inventive disclosures made herein, a user is able to perform “crunch”, “knee-up”, “compound crunch” and/or “torso twisting” exercise motions in which the spine is flexed forward in a curling path over an entire range of motion of the spine while providing both endurance repetition training and progressive resistance strength training. Furthermore, during use of an abdominal muscle exercise apparatus in accordance with embodiments of the inventive disclosures made herein, a user is able to sit comfortably, for example, in a chair and perform repetitions of abdominal muscle strengthening and endurance training exercises equivalent to conventional exercise techniques which target the abdominal rectus and oblique muscles while substantially limited physical stress to the regions of the spine, hip flexor muscles and joints.
- In an embodiment of the inventive disclosures made herein, an apparatus configured for exercising abdominal muscles of a user comprises an elongated support structure, a translatable member, a lower body support assembly and a lower body support lifting mechanism. The elongated support structure has a first end and a second end and the translatable member has a first end and a second end. The translatable member is slidably attached to the elongated support structure adjacent the first end of the elongated support structure for enabling translation of the translatable member with respect to the elongated support structure. The lower body support assembly is movably mounted on the elongated support structure adjacent the second end of the elongated support structure. The lower body support lifting mechanism is coupled between the first end of the translatable member and the lower body support assembly whereby translation of the translatable member toward the second end of the elongated support structure results in a corresponding upward movement of a lower body engaging portion of the lower body support assembly. In use, the user applies their upper body weight onto the translatable member, which results in a downward translation of the translatable member and upward movement of the lower body engaging portion of the lower body support assembly. Accordingly, in response to applying their upper body weight on the translatable member for translating the translatable member downward, the user performs a crunching action as they lift their lower body weight in reacting to the corresponding upward movement of the lower body engaging portion of the lower body support assembly on which their lower body (e.g., feet) are resting.
- In another embodiment of the inventive disclosures made herein, an apparatus configured for exercising abdominal muscles of a user comprises an elongated stanchion, a flexible link guide member, a translatable member, a lower body support assembly and a flexible link. The elongated stanchion has a first end and a second end and the translatable member has a first end and a second end. The flexible link guide member is attached to the elongated stanchion. A slidable portion of the translatable member is slidably attached to the elongated stanchion. The first end of the translatable member is disposed between the flexible link guide member and the second end of the elongated stanchion adjacent the first end of the elongated stanchion. The lower body support assembly includes a first end and a second end. The lower body support assembly is pivotally attached at the first end thereof to the elongated stanchion adjacent the second end of the stanchion. The flexible link has a first end attached to translatable member adjacent the first end of the translatable member, a second end attached to the lower body support assembly adjacent the second end of the lower body support assembly and an intermediate portion engaged with the flexible link guide member whereby downward translation of the shaft with respect to the shaft mount causes the lower body support to pivot relative to the elongated stanchion. In use, the user applies their upper body weight onto the translatable member, which results in a downward translation of the translatable member and upward movement of the lower body engaging portion of the lower body support assembly. Accordingly, in response to applying their upper body weight on the translatable member for translating the translatable member downward, the user performs a crunching action as they lift their lower body weight in reacting to the corresponding upward movement of the lower body engaging portion of the lower body support assembly on which their lower body (e.g., feet) are resting.
- In yet another embodiment of the inventive disclosures made herein, an apparatus configured for exercising abdominal muscles of a user comprises an elongated stanchion, a U-shaped support structure, a shaft mount, a flexible link guide member, an elongated shaft, a lower body support assembly and a flexible link. The U-shaped support structure is attached at a first end thereof to a first end of the elongated stanchion. The shaft mount is fixedly attached between legs of the U-shaped support structure adjacent a second end of the U-shaped support structure. The flexible link guide member is attached to at least one of the shaft mount and the U-shaped support structure adjacent the second end of the U-shaped support structure. A slidable portion of the elongated shaft is slidably engaged with the shaft mount for enabling translation of the elongated shaft with respect to the U-shaped support structure. A first end of the elongated shaft is disposed between the shaft mount and a second end of the elongated stanchion. The lower body support assembly is slidably mounted on the elongated stanchion intermediate the first end and the second end of the elongated stanchion. The flexible link has a first end thereof attached to the elongated shaft adjacent the first end of the elongated shaft, a second end thereof attached to the lower body support assembly and an intermediate portion thereof engaged with the flexible link guide member whereby the lower body support assembly translates along the elongated stanchion toward the first end of the elongated stanchion in response to translation of the elongated shaft relative to the shaft mount toward the second end of the elongated stanchion. In use, the user applies their upper body weight onto the elongated shaft, which results in a downward translation of the elongated shaft and upward movement of the lower body support assembly. Accordingly, in response to applying their upper body weight on the elongated shaft for translating the elongated shaft downward, the user performs a crunching action as they lift their lower body weight in reacting to the corresponding upward movement of the lower body support assembly on which their lower body (e.g., feet) are resting.
- Accordingly, an abdominal muscle exercise apparatus in accordance with at least one embodiment of the inventive disclosures made herein is configured for exercising the upper and lower portions of the rectus abdominus muscle. Furthermore, in accordance with at least one embodiment of the inventive disclosures made herein, such an abdominal muscle exercise apparatus is configured for exercising left and right internal and external oblique muscles which course medially and laterally respectively, to and from the lower rib cage and the front of the pelvic girdle. Still further, in accordance with at least one embodiment of the inventive disclosures made herein, such an abdominal muscle exercise apparatus is configured for enabling exercising oblique abdominal muscles by performing torso twisting crunching motion, which entail the user alternately twisting his or her torso trunk from left to right while depressing the translatable member downward and correspondingly lifting his or her legs in reaction to the lower body support assembly being displaced upwards.
- It is an object of an abdominal muscle exercise apparatus in accordance with at least one embodiment of the inventive disclosures made herein to provide a device for exercising the abdominal muscles without over-stressing the structures of the lower back, neck and the hip flexor muscles and while providing a means for both endurance training and strength training of the abdominal musculature.
- It is another object of an abdominal muscle exercise apparatus in accordance with at least one embodiment of the inventive disclosures made herein to permit the upper body to move forward under stress, in an arc configuration so as to enable a user to easily assume and maintain the proper crunch motion during exercise, thus distributing the flexure of the spine throughout the lumbo-sacral junction to the thoraco-lumbar junction of the spine so as to eliminate a focusing of undesirable flexure to any particular region of the lumbar spine.
- It is another object of an abdominal muscle exercise apparatus in accordance with at least one embodiment of the inventive disclosures made herein to provide a means to perform the “crunch”, “knee-up”, and “compound crunch “and” torso twisting motions without the discomfort or fatigue normally associated with the conventional supine method.
- It is another object of an abdominal muscle exercise apparatus in accordance with at least one embodiment of the inventive disclosures made herein to provide a single abdominal muscle exercise apparatus for performing complex “compound crunch” exercise safely and comfortably to target the upper and lower rectus abdominal muscle in a time saving manner such that when combined with the “torso twisting” exercises for the oblique abdominal muscles the crunch and knee-up exercises are not necessary and the entire abdominal musculature is exercised over a full range of motion.
- It is another object of an abdominal muscle exercise apparatus in accordance with at least one embodiment of the inventive disclosures made herein to avoid stress to the muscles of the neck and the cervical discs normally associated with the conventional supine method.
- It is another object of an abdominal muscle exercise apparatus in accordance with at least one embodiment of the inventive disclosures made herein to provide an abdominal muscle exercise apparatus whose inherent resistance is provided by the user's own lower body weight and which can be easily increased so as to accommodate users of different strength, and also provide a means of progressive resistance exercise for any individual users.

FIGS. 1-3 depict an abdominalmuscle exercise apparatus 1 in accordance with a first embodiment of the inventive disclosures made herein. Referring toFIGS. 1 and 2 , the abdominalmuscle exercise apparatus 1 includes a stanchion 2 (i.e., a suitably rigid) having atransverse bore 3 intermediate a head end 4 (i.e., a first end) and a foot end 5 (i.e., a second end) of thestanchion 2. Thefoot end 5 is attached to astanchion support member 6, which extends generally transverse to thestanchion 2. Thestanchion support member 6 includes a leftfree end 7 and a rightfree end 8 forming a horizontal leg of thestanchion 2, which provides stability to abdominalmuscle exercise apparatus 1 when engaged with a support surface (e.g., a floor). - The
head end 4 of thestanchion 2 is rigidly attached to a shaft mount 10 (e.g., a housing). Theshaft mount 10 includes atubular member 11 having abore 15 extending therethrough. Abushing 14 is fitted in atop end 12 and abottom end 13 of thebore 15. Brass and plastic are examples of materials from which thebushing 14 is made. Thestanchion 2 and theshaft mount 10 jointly represent an embodiment of an elongated support structure in accordance with the inventive disclosures made herein. - An elongated shaft 16 (i.e., a translatable member) includes a
slidable portion 16′ which is slidably disposed in thebore 15 of theshaft mount 10, a lower end 17 (i.e., a first end) disposed below theshaft mount 10 and a upper end 18 (i.e., a second end) that is attached to a generallytransverse handle 19 above theshaft mount 10. Preferably, theelongated shaft 16 is free to rotate within thebore 15 as well as translate within thebore 15. In other embodiments (not shown), an abdominal muscle exercise apparatus in accordance with the inventive disclosures made herein may benefit from theelongated shaft 16 being precluded from rotating. Thehandle 19 includes a leftfree end 20 and a rightfree end 21 which may be gripped by a user for applying a force to translate theelongated shaft 16 relative to theshaft mount 10. Accordingly, the free ends 20 and 21 are preferably covered with a resilient rubber, or other suitable material, so as to provide a gripping surface and comfort to the user. Thelower end 17 of theelongated shaft 16 is disposed between theshaft mount 10 and thefoot end 5 of thestanchion 2. - A
guide member retainer 22 for a flexiblelink guide member 23 includes a left flange 24 and a right flange 25 attached to thetubular member 11 of theshaft mount 10. Alternately, the pulleyguide member retainer 22 is attached to thestanchion 2. The flexiblelink guide member 23 is attached to theguide member retainer 22. A pulley or a roller rotatably mounted on theguide member retainer 22 and a non-rotating member having a low-friction contact surface mounted on theguide member retainer 22 are examples of the flexiblelink guide member 23. A bolt, a pin or other type of known fastener which extends through a bore in the flexible link guide member and theguide member retainer 22 is one example of a means for attaching the flexiblelink guide member 23 to theguide member retainer 22. - A pivot member 27 (e.g., a long bolt) is disposed through a bore 26 extending through each
leg 27 of afoot support assembly 28 and through thebore 3 of thestanchion 2. In this manner, thefoot support assembly 23 is pivotally mounted on thestanchion 2. Eachleg 27 of thefoot support assembly 28 has afirst end 30 adjacent the bore 26 and asecond end 31 attached to afoot support member 32. A foot engaging portion of thefoot support assembly 28 is provided by thefoot support member 32. Thefoot engaging portion 28 is configured for having one or both of a user's feet supported thereon. - It is disclosed herein that a foot support assembly as disclosed herein is an embodiment of a lower body support assembly, the foot engaging portion of the foot support assembly is an embodiment of a lower body engaging portion of the lower body support assembly and the foot support member is an embodiment of a lower body support member. In accordance with such embodiments, lower body support member of the lower body support assembly is configured for engaging (e.g., supporting) a user's foot, ankle, and/or other portion of the leg.
- Referring now to
FIGS. 1-3 , aflexible link 36 has afirst end 38 attached to theelongated shaft 16 adjacent itslower end 17, asecond end 40 attached to thefoot support assembly 28 and anintermediate portion 42 journalled around (i.e., engaged with) the flexiblelink guide member 23. In this manner, downward translation of theelongated shaft 16 results in corresponding pivoting action of thefoot support assembly 28 whereby thefoot support member 32 moves upward toward thehead end 4 of thestanchion 2. Accordingly, it can be seen that the flexiblelink guide member 23 serves to reverse movement direction of thesecond end 40 of theflexible link 36 relative to thefirst end 38 of theflexible link 36 and that a foot support lifting mechanism in accordance with an embodiment of the inventive disclosures made herein comprises the flexiblelink guide member 23 andflexible link 36. - A foot support lifting mechanism comprising a flexible link and flexible link guide member is a preferred embodiment of a lower body support lifting mechanism in accordance with the inventive disclosures made herein. It is disclosed herein that other embodiments of lower body support lifting mechanisms are contemplated and envisioned within the scope of the inventive disclosures made herein. In one alternate embodiment, a lower body support lifting mechanism in accordance with the inventive disclosures made herein utilizes a plurality of pivoting rigid members that are pivotally coupled, for example, between a lower body support assembly and a translating member that translates along a rigid stanchion, thereby enabling lower body lifting functionality to be accomplished. In another alternate embodiment, a lower body support lifting mechanism in accordance with the inventive disclosures made herein utilizes a plurality of rotating drive members (e.g., enmeshed gears) that are coupled, for example, between a lower body support assembly and a translating member that translates along a rigid stanchion, thereby enabling lower body lifting functionality to be accomplished.
- An example of the
flexible link 36 is a length of essentially inelastic (i.e., flexible, but non-elongating) rope, cable, woven webbing or the like. As depicted inFIGS. 1-3 , theflexible link 36 has a fixed, predetermined length. However, in other embodiments (not shown), the length of the flexible link is adjustable. - A pair of resilient resistance members 44 (
FIGS. 1 and 2 ) is removably attached to thestanchion 2 and thefoot support assembly 28. Specifically, as depicted inFIGS. 1 and 3 , a first portion 46 (e.g., a first end) of the each one of theresilient resistance members 44 is removably attached to thestanchion support member 6 and a second portion 48 (e.g., a second end) of each one of theresilient resistance members 44 is removably attached to thefoot support member 32 of thefoot support assembly 28. In this manner, theresilient resistance members 44 enable a resistive force to be exerted for counteracting pivoting of thefoot support assembly 28 relative to thestanchion 2. - The pair of
resilient resistance members 44 is an embodiment of a means for imparting resistance that is connected between an elongated support structure and a foot support assembly in accordance with the inventive disclosures made herein. Embodiments of such means may be connected between such elongated support structure and such foot support assembly in any number of conceivable configurations. It is contemplated that less than or more than a pair of theresilient resistance members 44 may be utilized for imparting such resistance. Loops of resilient material and molded resilient bands are examples of theresilient resistance members 44. Alternative embodiments of such means for imparting resistance in accordance with the inventive disclosures made herein include spring devices, hydraulic devices, flexible rod devices, a provision for attaching free weights to thefoot support assembly 28 and/or theflexible link 36, or any other conceivable isotonic or isokinetic resistance device that can be suitable incorporated. - The purpose of such a means for imparting resistance means is to provide additional resistance against downward translation of the
elongated shaft 16 such that, when theelongated shaft 16 is pushed down into for achieving a crunch position, force generated by the means for imparting resistance combined with the user's weight resting onfoot support member 32 resists the upward pivoting offoot support assembly 28 and downward translation of theelongated shaft 16. Such means for imparting resistance may be configured for being replaceable or adjustable for enabling imparted resistance to be alterable (i.e., changeable, variable and/or adjustable). For example, the user may alter the imparted resistance by removing one or both of theresilient resistance members 44, exchanging theresilient resistance members 44 with different resilient resistance members that have a different resistance rates, or installing additional resilient resistance members in addition to theresilient resistance members 44. Furthermore, it is contemplated herein that such means for imparting resistance may be coupled between a support structure and translatable member of an exercise apparatus in accordance with the inventive disclosures made herein. - As depicted in
FIG. 4 , it may be seen that the user's lower body weight on thefoot support member 32 of thefoot support assembly 28 combined with engagement of theresilient resistance members 44 provides a resistive force to the downward displacement ofelongated shaft 16. It can also be seen that, through the orientationflexible link 36 and the flexiblelink guide member 22, downward translation of theelongated shaft 16 from a static handle position S1 to a compressed handle position C results in pivoting of thefoot support assembly 28 and corresponding upward movement of thefoot support member 32 from a foot assembly static position S2 to a lifted position L. Accordingly, by the user pressing downwardly on thehandle 19 in a curling crunch motion, he or she is able to easily execute a compound crunch and exercise the rectus abdominal muscle. By pressing downwardly on thehandle 19 in a curling crunch motion while twisting alternately to the right or left sides, the user is able to execute torso twisting for exercising the oblique abdominal muscles. - Referring now to
FIG. 5 , an abdominalmuscle exercise apparatus 100 in accordance with a second embodiment of the inventive disclosures made herein is depicted. The abdominalmuscle exercise apparatus 100 includes aU-shaped support structure 101, astanchion 102, a stanchion support member 106, ashaft mount 110, anelongated shaft 116, atransverse handle 119, aguide member retainer 122, a flexible link guide member (not specifically shown), afoot support assembly 128, aflexible link 136 andresilient resistance members 144. Thestanchion 102 includes ahead end 104 and a foot end 105. TheU-shaped support structure 101 is attached at a first end 101 a (i.e., its closed end) to thehead end 104 of thestanchion 102. Theshaft mount 110 is attached to a second end 101 b of theU-shaped support structure 101 between spaced apart legs 101 c of theU-shaped support structure 101. - The
guide member retainer 122 is attached to theshaft mount 110. Alternately, the pulleyguide member retainer 122 is attached to one or both of the spaced apart legs 101 c of theU-shaped support structure 101. The flexible link guide member is attached to theguide member retainer 122. Theelongated shaft 116 is slidably mounted on theshaft mount 110, thereby enabling the elongated shaft to translate with respect to theU-shaped support structure 101. Thefoot support assembly 128 includes a collar 128 a that is slidably attached to thestanchion 102, thereby enabling thefoot support assembly 128 to translate with respect to thestanchion 102. - The
flexible link 136 has afirst end 138 attached to theelongated shaft 116 adjacent its lower end 117, asecond end 140 attached to thefoot support assembly 128 and anintermediate portion 142 journalled around (i.e., engaged with) the flexible link guide member. In this manner, downward translation of theelongated shaft 116 results in corresponding pivoting action of thefoot support assembly 128 whereby afoot support member 132 of thefoot support assembly 128 moves upward toward thehead end 104 of thestanchion 102. Accordingly, it can be seen that the flexible link guide member serves to reverse movement direction of thesecond end 140 of theflexible link 136 relative to thefirst end 138 of theflexible link 136 and that a foot support lifting mechanism in accordance with an embodiment of the inventive disclosures made herein comprises the flexible link guide member andflexible link 136. - A pair of
resilient resistance members 144 is removably attached to thestanchion 102 and thefoot support assembly 128. Specifically, a first portion 146 (e.g., first end) of the each one of theresilient resistance members 144 is removably attached to the stanchion support member 106 and a second portion 148 (e.g., a second end) of each one of theresilient resistance members 144 is removably attached to thefoot support member 132 of thefoot support assembly 128. In this manner, theresilient resistance members 144 enable a resistive force to be exerted for counteracting pivoting of thefoot support assembly 128 relative to thestanchion 12. - Referring to
FIG. 6 , a user mounts and operates theabdominal muscle apparatus 100 in a similar manner as described in reference toFIG. 4 . However, functionality of the abdominalmuscle exercise apparatus 100 depicted inFIGS. 5 and 6 is different than functionality of the abdominal muscle exercise apparatus 1-4. Specifically, lifting action of thefoot support member 132 from a foot assembly static position S2 to a lifted position L is accomplished by translation of thefoot support assembly 128 along thestanchion 102 rather than by pivoting action in response to translating thehandle 119 from a static handle position S1 to a compressed handle position C. -
FIGS. 7 and 8 depict an abdominalmuscle exercise apparatus 200 in accordance with a third embodiment of the inventive disclosures made herein. The abdominalmuscle exercise apparatus 200 exhibits similar overall function to the abdominalmuscle exercise apparatus 1 depicted inFIGS. 1-4 and has a similar overall construction. However, with respect to the abdominal muscle exercise apparatus depicted inFIGS. 1-4 and as discussed in greater detail below, the abdominalmuscle exercise apparatus 200 depicted inFIGS. 7 and 8 comprises a distinctive means for imparting resistance and a distinctive foot supporting arrangement. - The abdominal
muscle exercise apparatus 200 includes astanchion 202 having a head end 204 (i.e., a first end) and a foot end 205 (i.e., a second end). Thefoot end 205 is attached to astanchion support member 206, which extends generally transverse to thestanchion 202. The head end 204 ofstanchion 202 is rigidly attached to ashaft mount 210. Theshaft mount 210 includes atubular member 211 having abore 215 extending therethrough. - An elongated shaft 216 (i.e., a translatable member) includes a
slidable portion 216′ which is slidably disposed in thebore 215 of theshaft mount 210, a lower end 217 (i.e., a first end) disposed below theshaft mount 210 and a upper end 218 (i.e., a second end) that is attached to a generallytransverse handle 219 above theshaft mount 210. Preferably, theelongated shaft 216 is free to rotate within thebore 215 as well as translate (i.e., linear translation) within thebore 215. Thelower end 217 of theelongated shaft 216 is disposed between theshaft mount 210 and thefoot end 205 of thestanchion 202. Aguide member retainer 222 for a flexible link guide member (not specifically shown) is attached to thetubular member 211 of theshaft mount 210. Alternatively, the guide member retainer may be attached to thestanchion 202. The flexible link guide member (e.g., a pulley, roller or non-rotating member having a low-friction contact surface) is attached to theguide member retainer 222. - A pivot member 225 (e.g., a long bolt) is disposed through a
bore 226 extending through eachleg 227 of afoot support assembly 228 and through abore 229 of thestanchion 202. In this manner, thefoot support assembly 228 is pivotally mounted on thestanchion 202. Eachleg 227 of thefoot support assembly 228 has afirst end 230 adjacent thebore 226 of thestanchion 202 and asecond end 231 attached to across member 235. A foot engaging portion of thefoot support assembly 228 is provided by thefoot support member 232. Thefoot support member 232 is pivotally mounted on thelegs 227 of thefoot support assembly 228 for enabling thefoot support member 232 to be moved between a plurality of foot support member positions (e.g., a first position P1 and a second position P2). The ability to select between a plurality of foot support member positions is advantageous in that it allows the abdominalmuscle exercise apparatus 200 and associated exercise technique to be customized and/or optimised dependent upon parameters specific to a given user. - A
flexible link 236 has a first end 238 attached to theelongated shaft 216 adjacent itslower end 217, asecond end 240 attached to thefoot support assembly 228 and anintermediate portion 242 journalled around (i.e., engaged with) the flexible link guide member. In this manner, downward translation of theelongated shaft 216 results in corresponding pivoting action of thefoot support assembly 228 whereby thefoot support member 232 moves upward toward the head end 204 of thestanchion 202. Accordingly, it can be seen that the flexible link guide member serves to reverse movement direction of thesecond end 240 of theflexible link 236 relative to the first end 238 of theflexible link 236 and that a foot support lifting mechanism in accordance with an embodiment of the inventive disclosures made herein comprises the flexible link guide member andflexible link 236. - A pair of
resilient resistance members 244 is removably attached to thestanchion 202 and thefoot support assembly 228. Specifically, as depicted inFIGS. 7 and 8 , thestanchion 202 includes aresistance member mount 260 and eachleg 227 of thefoot support assembly 228 includes aresistance member mount 262. A first portion 246 (e.g., a first end) of the each one of theresilient resistance members 244 is removably attached to theresistance member mount 260 of thestanchion 202 and a second portion 248 (e.g., a second end) of each one of theresilient resistance members 244 is removably attached to theresistance member mount 262 of thefoot support apparatus 228. In this manner, theresilient resistance members 244 enable a resistive force to be exerted for counteracting pivoting of thefoot support assembly 228 relative to thestanchion 202. For enabling resistance imparted by the resilient resistance members to be alterable, it is contemplated that thefirst portion 246 of theresilient resistance members 244 could be removably attached to thestanchion support member 206 rather than theresistance member mount 260 of thestanchion 202 or that thesecond portion 248 of each one of theresilient resistance members 244 could be removably attached to thecross member 235 rather than to theresistance member mount 262 of thefoot support apparatus 228. - Certain structural components and/or assemblies (e.g., the elongated support structure, the foot support assembly, the translatable member and certain related components) of abdominal muscle exercise apparatuses in accordance with embodiments of the disclosures made herein may be custom manufactured articles fabricated using known fabrication techniques, proprietary fabrication techniques, commercially available materials and/or proprietary materials. Steel tubing is one choice for such structural components and/or assemblies. Such components and/or assemblies made from steel tubing may be fabricated using known operations such as cutting, drilling, turning, milling, die casting, extruding, welding and/or bending using proprietary and/or commercially available equipment. Plastic is another choice for certain structural components and/or assemblies. Such components and/or assemblies made from plastic may be fabricated using known operations such as molding, extrusion, vacuum forming, cutting, drilling, turning, milling, thermal forming, and/or ultrasonic welding using proprietary and/or commercially available equipment. Furthermore, certain components (e.g., the flexible link guide member, flexible link, resilient resistance members, bushings, etc) will be off-the-shelf items that are purchased as generic, already-manufactured articles.
