Opposing left and right side assemblies of slidable wedge 30 are connected by wedge cross brace 31. Upper body user support assembly 50 pivots on upper body user support pivot 58. Upper body user support 50 is a pivotal assembly consisting of head pad 56, torso pads 55, an upper body user support pivoting cross bar 51, upper body user support cable anchor mount bar 45B, an upper body user support hand grip mounting bar 52 with attached grip pulling bars 57 for receiving the user U's hands. Lower body user support assembly 60 pivots on lower body user support pivot 63. Lower body user support 60 is a pivotal assembly consisting of lower body user support pivoting cross bar 61, lower body user support pivot connection bars 62, lower body user support pivots 63, seat bearing mounting bar 64, seat pivot shaft 65, seat pivot bearings 66, seat support bar 67, seat pad 73, lumbar pad support bar 70, lumbar pad 72, ankle pad support bar 69, ankle pad mounting bar 75, ankle pads 74 for receiving a user's feet and ankles. Upper body user support assembly 50 and lower body user support assembly 60 are guided and partially supported by user support linkage assembly 25 wherein link bar 26 is connected at a first end to base frame 11 at link bar pivot 29A and connected at a second end to upper body user support 50 at link bar pivot 29B and link bar 27 is connected at a first end to pivot bearing support tube 61 at link bar pivot 29D and connected at a second end to upper body user support 50 at link bar pivot 29C and link bar 28 is connected at a first end to upper to lower body user support pivot connection mount bar 59 at link bar pivot 29F and connected at a second end to upper to lower body user support pivot connection mount bar 59 at link bar pivot 29E. Upper body user engagement assembly 80A and lower body user engagement assembly 80B are operatively connected to slidable wedge 30 by drive linkage assembly 40 wherein drive cable 41 has a first end and a second end and a first end is connected to upper body user support assembly 50 at upper body user support cable anchor 42B and a second end is connected to lower body user support assembly 60 at lower body user support cable anchor 42A and a central portion of drive cable 41 is connected to slidable wedge 30 and to base frame cross brace 12 by guide pulley housings 43 and guide pulleys 44. Although not illustrated so as to more clearly present the various components of this embodiment, this embodiment of the invention can be configured to add additional resistance to the exercise motion of machine 10 wherein weight disc holder bars 91 could be rigidly attached to movable slide support surfaces 14 or any other suitable portion of the machine for supporting removable weight discs 92, and or weight stack assembly 98 could be operatively linked to the exercise motion of machine 10 or alternative resistance features could be added to machine 10.

[0058] To operate this embodiment of the invention, the user U enters machine 10 and assumes a generally seated position in which seat pad 73 and lumbar pad 72 supports user U's upper legs, buttocks and hips. User U's torso is supported by torso pads 55 and user U's head is support by head pad 56. User U then places his or her feet behind ankle pads 74 such that the front of user U's ankles are contacting and braced against pads 74. To activate and engage machine 10, user U grasp hand grip pull bars 57 which are rigidly attached to upper body user support assembly 50, and pulls them in a forward arcing motion while concurrently pulling on ankle pads 74 which are rigidly attached to lower body user support assembly 60 in an upward arcing motion, thus concurrently pivoting upper body user engagement member 50 about upper body user support pivot 58 and lower body user support 60 about lower body user support pivot 63. This motion concurrently acts upon drive linkage assembly 40 causing lower body user support cable anchor 42A to move forward and away from slidable wedge 30 and upper body user support cable anchor 42B to move rearward transferring the rearward portion of drive cable 41 into a more vertical orientation such that slidable wedge 30 is forced to roll along movable slide support surface 14 and stationary slide support surface 13 in a direction rearward towards movable slide support surface pivot 15. This motion of slidable wedge 30 concurrently causes movable slide support surface 14 to pivot about pivot 15 in an upward arcing motion. This motion concurrently activates user support linkage assembly 25 wherein link bar 26 guides upper body user support 50 in a rearward and downward motion and link bar 27 stabilizes upper body user support 50 as it moves and link bar 28 connects upper body user support 50 and lower body user support 60 such that they move in unison causing lower body user support to move in an upward and rearward motion. This concurrent arcing and articulating motion of upper body user support 50 and lower body user support 60 that occurs when the user U exerts a pulling force on hand grip pull bars 57 and ankle pads 74 causes user U to move from a generally seat orientation in the at rest and inactivated position where the angle formed between user U's thighs and torso is a wide V shape to a contracted crunch orientation where the angle formed between user U's thighs and torso is a narrow V shape in the engaged and fully activated position. User U can maintain the position of upper body user support 50 and lower body user support 60 at any location between the at rest position and the fully activated position during the exercise motion.

[0059] At any time during the exercise motion when user U decreases the pulling force upon hand grip pull bars 57 and ankle pads 74, user support linkage 25 will guide upper body user support 50 in a forward and upward motion as it pivots about upper body user support pivot 58 while lower body user support 60 concurrently moves in a downward and forward motion as it pivots about lower body user support pivot 63, and slidable wedge 30 will concurrently roll forward on movable slide support surface 14 and stationary slide support surface 13 and away from pivot assembly 15 causing movable slide support surface 14 to pivot about pivot assembly 15 in a downward arcing motion this will concurrently cause lower body user support cable anchor 42A to move downward and closer to slidable wedge 30 and upper body user support cable anchor 42B to move forward into a more angular orientation. This concurrent arcing and articulating motion of upper body user support 50 and lower body user support 60 that occurs when the user U reduces a pulling force on hand grip pull bars 57 and ankle pads 74 causes user U to move from a generally contracted crunch orientation where the angle formed between user U's thighs and torso is a narrow V shape in the engaged and fully activated position to a more seat orientation in the at rest and inactivated position where the angle formed between user U's thighs and torso is a wide V shape.

[0060] User U can perform multiple repetitions of urging and releasing the force required to operate this embodiment of the machine 10 so as to perform a set of abdominal muscle exercises. The multi-dimensional articulating motion of upper body user support 50 and lower body user support 60 in this embodiment creates a greater range of motion that more closely assimilates a natural crunching motion of the user U's abdominal muscles thus creating an improved and more effective way to exercise the user U's abdominal muscles.

[0061] Referring now to FIGS. 9-15, which represent an embodiment of the invention that exercises user U's pectoral muscles wherein opposing left and right sides of stationary base frame 11 are connected by base frame cross braces 12 and stationary slide support surfaces 13 are rigidly connected to base frame 11 to form the foundation base structure of machine 10. Movable slide support surfaces 14 are pivotally connected to a rearward portion of base frame 11 at pivot assembly 15 located on a base frame cross brace 12. A rearward portion of movable slide support surfaces 14 are located below stationary slide support surfaces 13 relative to base frame 11 and a forward portion of movable slide support surfaces 14 are located above stationary slide support surfaces 13 relative to base frame 11 and both movable slide support surfaces 14 and stationary slide support surfaces 13 are operatively connected by slidable wedge assembly 30 such that upper wheels assembly 39 is engaged with movable slide support surfaces 14 and opposing left and right lower wheels assemblies 38 are engaged with stationary slide support surfaces 13 and upper wheels assembly 39 and lower wheels assemblies 38 are connected by wedge axle frame 32 and wedge axles 33. A forward portion of user support assembly 20 pivots on movable slide support surface 14 at lower user support pivots 24A and a rearward portion of user support assembly 20 pivots on user support linkage assembly 25 at upper user support pivot 24B. User support assembly 20 is comprised of torso pad 55 mounted on torso pad mounting plate 18, seat pad 73 is mounted on seat pad mounting plate 19, user support connection flanges 23, foot support connection bar 21 and foot support 22. Upper body user engagement assembly 80A is comprised of opposing left and right press grip handles 84 rigidly connected proximal to a first end of lower press arm link bar 84 and a second end of lower press arm link bar 84 is pivotally connected to a first end of upper press arm link bar 83 at press arm pivot 82B and a second end of upper press arm pivot 83 is pivotally connected to press arm assembly connection bar 88 at press arm pivot 82A. User support linkage assembly 25 is comprised of slidable wedge to user support link bar 126 having a first end pivotally connected to user support 20 at user support connection flange 23 with upper user support pivot 24B and pivotally connected at a second end to a rear portion of slidable wedge assembly 30 at slidable wedge link bar pivot 129. Drive linkage assembly 40 is comprised of a press arm cable 81 connected at a first and second ends to opposing left and right pressing arm cable anchors 142 and guided by a centrally located guide pulley 44 that is mounted on floating guide pulley housing 43 and drive cable 41 having first and second ends is connected at a first end to floating housing 43 at drive cable anchor 143 and connected at a second end to a rearward portion of slidable wedge 30 with drive cable anchor 143 and guided by guide pulley 44 mounted on guide pulley housing 43 which is rigidly attached to base frame cross base 12. FIGS. 11, 12, 13 illustrate this embodiment with additional resistance provided by removable discs 92 supported by weight disc holder bar 91 which is rigidly attached to movable slide support surfaces 14 with connection bracket 90. Although not illustrated removable weight discs 92 and weight disc bar holder 92 could be mounted at various locations on machine 10 to create additional resistance and or weight stack assembly 98 could be operatively linked to the exercise motion of machine 10 or alternative resistance features could be added to machine 10.

[0062] To operate this embodiment of the invention, the user U enters machine 10 and assumes a generally seated position in which seat pad 73 supports user U's upper legs, buttocks and hips and user U's torso is supported by torso pad 55. User U then places his or her feet on foot support 22 and grasp press arm grip handles 85. To activate and engage machine 10, user U presses press arm grip handles 85, which are rigidly attached to a first end of lower press arm link bars 84 forward and away from torso pad 55. This motion concurrently causes upper press arm link bars 83, which are pivotally connected at a first end to a second end of lower press arm link bars 84 at lower press arm pivots 82B. This causes upper press arm link bars 83 to pivot at a second end in a forward and upward arcing motion about upper press arm pivots 82A. This motion concurrently causes press arm cable 82 and floating guide pulley 44 to move forward and away from a rearward portion of machine 10 and act upon drive cable 41, which is attached at a first end to floating guide pulley housing 43 and attached at a second end to a rearward portion of slidable wedge assembly 30 such that slidable wedge 30 and slidable wedge to user support link bar 126 move in a direction towards a rearward portion of machine 10 causing upper wedge wheels assembly 39 to move movable slide support surfaces 14 in an upward arcing pivoting motion about movable slide support surface pivot assemblies 15 thereby causing a forward portion of user support 20 to pivot about lower user support pivot 24A and a rearward portion of user support 20 to pivot about upper user support pivot 24B such that user support 20 and user U move from a first at rest and inactivated seated position through a multi-dimensional articulating motion and into a more elevated and reclined position relative to stationary base frame 11 in the fully engaged and activated position. User U can maintain press arm grip handles 85 and user support 20 at any location between the at rest position and the fully activated position during the exercise motion. An additional operational feature of machine 10 in this pectoral exercise machine embodiment is that during operation of machine 10, the opposing left and right sides of upper body user engagement assembly 80A can operate independently of one another such that either side can be moved anywhere between the at rest and inactivated position and fully engaged and activated position, however the motion of user support 20 is maximized when both the left and right sides of upper body user engagement assembly 80A are moved equal distances.

[0063] At any time during the exercise motion when user U decreases the pressing force upon either the left or right press arm grip handles 85 user support 20 and user U move through a multi-dimensional articulating motion into a less elevated and less reclined position relative to stationary base frame 11 wherein a forward portion of user support 20 pivots about lower user support pivot 24A and a rearward portion of user support 20 pivots about upper user support pivot 24B causing movable slide support surfaces 14 to move in a downward arcing pivoting motion about movable slide support surface pivot assemblies 15 and slidable wedge 30 and slidable wedge to user support link bar 126 to move in a direction towards a forward portion of machine 10 which acts upon drive cable 41 which acts upon floating pulley housing 43 causing floating pulley 44 and press arm drive cable 81 to move in a direction towards a rearward portion of machine 10, causing a second end of upper press arm link bar 83 to pivot about upper press arm pivot 82A and a second end of lower press arm link bar 84 to pivot about a first end of upper press arm link 83 at lower press arm pivot 82B such that press arm grip handles 85 which are rigidly connected to a first end of lower press arm link bar 84 move towards torso pad 55 causing user U to move from a more elevated and reclined position in the engaged and activated position to a more seat position in the at rest and inactivated position.

[0064] User U can perform multiple repetitions of urging and releasing the force required to operate this embodiment of the machine 10 so as to perform a set of pectoral muscle exercises. The multi-dimensional articulating motion of user support 20 in this embodiment creates a greater range of motion that more closely assimilates a natural pressing and contracting motion of the user U's pectoral muscles thus creating an improved and more effective way to exercise the user U's pectoral muscles.

[0065] Now referring to FIGS. 15-20, which represent an embodiment of the invention that exercises user U's latissimus dorsi muscles wherein opposing left and right sides of stationary base frame 11 are connected by base frame cross braces 12 and stationary slide support surfaces 13 are rigidly connected to base frame 11 to form the foundation base structure of machine 10. Movable slide support surfaces 14 are pivotally connected to a rearward portion of base frame 11 at pivot assembly 15 located on a base frame cross brace 12. At least a portion of movable slide support surfaces 14 are located above stationary slide support surfaces 13 relative to base frame 11 and both movable slide support surfaces 14 and stationary slide support surfaces 13 are operatively connected by slidable wedge assembly 30 such that upper wheels assembly 39 is engaged with movable slide support surfaces 14 and opposing left and right lower wheels assemblies 38 are engaged with stationary slide support surfaces 13 and upper wheels assembly 39 and lower wheels assemblies 38 are connected by wedge axle frame 32 and wedge axles 33. A rearward upper portion of user support assembly 20 pivots on movable slide support surface 14 at upper user support pivots 24B and a rearward lower portion of user support assembly 20 pivots on user support linkage assembly 25 at lower user support pivots 24A wherein upper user support pivots 24B and lower user support pivots 24A are approximately vertical of one another and equal distances from either end of machine 10. User support assembly 20 is comprised of a thigh hold down pad 76 mounted on thigh pad support bar 77, seat pad 73 mounted on seat support bar 67, user foot support 22 mounted on thigh pad support bar 77 and connection flanges 23. Upper body user engagement assembly 80A is comprised of opposing left and right pulldown bar grip pulling bars 102 rigidly connected proximal to a first forward end of pulldown bars 100 and central portion of pulldown bars 100 are rigidly connected with pulldown bar cross brace 100 and a second rearward end of pulldown bars 100 are pivotally connected to stationary base frame 11 at pulldown bar pivots 103. User support linkage assembly 25 is comprised of opposing left and right slidable wedge to user support link bars 126 having a first end pivotally connected to user support 20 at user support connection flanges 23 with lower user support pivots 24A and pivotally connected at a second end to a central portion of slidable wedge assembly 30 at slidable wedge link bar pivot 129. Drive linkage assembly 40 is comprised of a drive cable 41 that is connected at a first end to central portion of pulldown bar cross brace 101 with a drive cable anchor 143 and connected at a second end to a rearward portion of slidable wedge assembly 30 with a drive cable anchor 143 and guided by an upper guide pulley 44 that is housed in a guide pulley housing 43 which is mounted on a base frame cross brace 12 and a lower guide pulley 44 that is housed in a guide pulley housing 43, which is mounted on a base frame cross brace 12. Additional resistance to the exercise motion is provided by removable discs 92 supported by weight disc holder bars 91 which are rigidly attached to movable slide support surfaces 14. Although not illustrated removable weight discs 92 and weight disc bar holder 92 could be mounted at various locations on machine 10 to create additional resistance and or weight stack assembly 98 could be operatively linked to the exercise motion of machine 10 or alternative resistance features could be added to machine 10.

[0066] To operate this embodiment of the invention, the user U enters machine 10 by grasping left and right pulldown bar grip pulling bars 102 and assumes a generally seated position in which seat pad 73 supports user U's upper legs, buttocks and hips and torso. User U then places his or her feet on foot support 22 and places his or her thighs below thigh hold down pad 76 such that thigh hold down pad 76 and foot support 22 hold user U's lower body securely in place during the exercise motion. To activate and engage machine 10, user U pulls pulldown bar grip pulling bars 102 downward towards user U's chest this motion causes pulldown bars 100 to arc downward about pulldown bar pivots 103 which concurrently acts upon drive cable 41 which is attached at a first end to pulldown bar cross brace 100 and attached at a second end to a rearward portion of slidable wedge assembly 30 such that slidable wedge 30 moves in a direction towards a rearward portion of 10 this causes user support 20 and user U to pivot about upper user support pivots 24B and lower user support pivots 24A such that lower user support pivot 24A moves a greater horizontal distance towards a rearward portion of machine 10 relative to base frame 11 than upper user support 24B such that lower user support 24A moves closer to a rearward portion of machine 10 than upper user support 24B thus causing user support 20 and user U to move from a first at rest and inactivated mostly upright and vertical seated position relative to base frame 11 through a multi-dimensional articulating motion and into a more reclined position relative to stationary base frame 11 in the fully engaged and activated position. User U can maintain pulldown bar grip pulling bars 102 and user support 20 at any location between the at rest position and the fully activated position during the exercise motion.

[0067] At any time during the exercise motion when user U decreases the pulling force upon pulldown bar grip pulling bars 102, slidable wedge assembly 30 will move in a direction away from a rearward portion of machine 10 and act upon drive cable 41 which is connected at a second end to a rearward portion slidable wedge 30 and connected at a first end to pulldown bar cross brace 101 and guided by guide pulleys 44 thus causing pulldown bars 100 to move in a downward arcing motion and slidable wedge to user support link bars 126 and movable slide support surfaces 14 will concurrently pivot in an downward arcing motion about slidable wedge link bar pivots 129 and movable slide support surface pivots 15 respectively. This will cause user support 20 and user U to pivot about lower user support pivots 24A and upper user support pivots 24B such that lower user support pivot 24A moves a greater horizontal distance away from a rearward portion of machine 10 relative to base frame 11 than upper user support 24B such that lower user support 24A and upper user support pivots 24B are positioned approximately vertical of one another and equal distances from either end of machine 10 in the at rest and inactivated position. This motion takes user U through a multi-dimensional articulating motion from a more reclined position relative to stationary base frame 11 in the engaged and fully activated position to a mostly upright and vertical seated position relative to base frame 11 in the at rest and inactivated position.

[0068] User U can perform multiple repetitions of urging and releasing the force required to operate this embodiment of the machine 10 so as to perform a set of latissimus dorsi muscle exercises. The multi-dimensional articulating motion of user support 20 in this embodiment creates a greater range of motion that more closely assimilates a natural pressing and contracting motion of the user U's latissimus dorsi muscles thus creating an improved and more effective way to exercise the user U's latissimus dorsi muscles.

[0069] Now referring to FIGS. 21-26, which represent an embodiment of the invention that exercises user U's quadriceps muscles wherein opposing left and right sides of stationary base frame 11 are connected by base frame cross braces 12 and stationary slide support surfaces 13 are rigidly connected to base frame 11 to form the foundation base structure of machine 10. Movable slide support surfaces 14 are pivotally connected to a rearward portion of base frame 11 at pivot assembly 15 located on a base frame cross brace 12. A rearward portion of movable slide support surfaces 14 are located below stationary slide support surfaces 13 relative to base frame 11 and a forward portion of movable slide support surfaces 14 are located above stationary slide support surfaces 13 relative to base frame 11 and both movable slide support surfaces 14 and stationary slide support surfaces 13 are operatively connected by slidable wedge assembly 30 such that upper wheels assembly 39 is engaged with movable slide support surfaces 14 and opposing left and right lower wheels assemblies 38 are engaged with stationary slide support surfaces 13 and upper wheels assembly 39 and lower wheels assemblies 38 are connected by wedge axle frame 32 and wedge axles 33. For this embodiment wedge axle frame 32 comprises open cut away sections to allow drive cable 41 to move unobstructed through wedge axle frame 32 during operation of machine 10. A forward portion of user support assembly 20 pivots on movable slide support surface 14 at lower user support pivots 24A and a rearward portion of user support assembly 20 pivots on user support linkage assembly 25 at upper user support pivot 24B. User support assembly 20 is comprised of torso pad 55 mounted on torso pad support bar 78 and seat pad 73 is mounted on seat support bar 67. Lower body user engagement assembly 80B is comprised of ankle pad pivot bar 79 pivotally mounted at a first end to ankle pad bar pivot 87 and ankle pads 74 are mounted proximal to a second end of ankle pad pivot bar 79 and drive cable anchor mounting bracket 48 is rigidly attached to a lower rearward portion of ankle pad pivot bar 79 relative to base frame 11. User support linkage assembly 25 is comprised of slidable wedge to user support link bar 126 having a first end pivotally connected to user support 20 at user support connection flange 23 with upper user support pivot 24B and pivotally connected at a second end to a rearward portion of slidable wedge assembly 30 at slidable wedge link bar pivot 129. Drive linkage assembly 40 is comprised of a drive cable 41 that is connected at a first end to drive cable mounted bracket 48 with a drive cable anchor 143 and connected at a second end to a rearward portion of slidable wedge assembly 30 with a drive cable anchor 143 and guided by an upper guide pulley 44 that is mounted on a base frame cross brace 12 and a lower guide pulley 44 that is mounted on a base frame cross brace 12. Additional resistance is provided by weight stack assembly 98 wherein weight stack cable 46 has a first and second ends such that a first end is connected to a forward portion of slidable wedge 30 with a weight stack cable anchor 47 and a second end is connected to a first upper end of weight stack selector rod 96 with a weight stack cable anchor 47 and guided by a first guide pulley 44 housed in guide pulley housing 43 mounted on a forward base frame cross brace 12 and guided by a second guide pulley 44 housed in guide pulley housing 43 mounted on a rearward base frame cross brace and guided by a third and fourth guide pulleys 44 housed in a guide pulley housing 43 mounted on an upper portion of weight stack frame 93. Weight stack plates 95 are guided by and connected to weight stack frame 93 by weight stack guide rods 94 which are connected to weight stack frame 93 and weight stack selector pin 97 can be inserted through any weight stack plate 95 and weight stack selector rod 96 such that user U can select a desired amount of resistance weight. Although not illustrated removable weight discs 92 and weight disc bar holder 92 could also be mounted at various locations on machine 10 to create additional resistance and or alternative resistance features could be added to machine 10.

[0070] To operate this embodiment of the invention, the user U enters machine 10 and assumes a seated position in which seat pad 73 supports user U's upper legs, buttocks and hips and user U's torso is supported by torso pad 55. User U then places his or her ankles against a rearward portion of ankle pads 74 and grasps user stabilization grip bars 86. To activate and engage machine 10, user U extends his or her lower legs forward such that his or her ankles moves ankle pads 74 and a second end of ankle pad pivot bar 79 in an upward arcing motion away from seat pad 73 as a first end of ankle pad pivot bar 79 pivots about ankle pad bar pivot 87, this motion acts upon drive cable 41 which is attached at a first end to drive cable anchor mounting bracket 48 and attached at a second end to a rearward portion of slidable wedge assembly 30 such that slidable wedge 30 and slidable wedge to user support link bar 126 move in a direction towards a rearward portion of machine 10 causing upper wedge wheels assembly 39 to move movable slide support surfaces 14 in an upward arcing pivoting motion about movable slide support surface pivot assemblies 15 thereby causing a forward portion of user support 20 to pivot about lower user support pivot 24A and a rearward portion of user support 20 to pivot about upper user support pivot 24B such that user support 20 and user U move from a first at rest and inactivated seated position through a multi-dimensional articulating motion and into a more elevated and reclined position relative to stationary base frame 11 in the fully engaged and activated position. User U can maintain ankle pad pivot bar 79 and user support 20 at any location between the at rest position and the fully activated position during the exercise motion. Additionally when slidable wedge assembly 30 moves in a rearward direction it concurrently acts upon weight stack cable 46 which is attached at a first end to a forward portion of slidable wedge assembly 30 with a weight stack cable anchor 47 and attached at a second end to an upper first end of weight stack selector rod 96 with a weight stack cable anchor 47 such that at least a portion of weight stack plates 95 along with weight stack selector rod 96 and weight stack selector pin 97 move in a vertical upward motion guided by weight stack guide rods 94 so as to provide additional resistance to the exercise motion.

[0071] At any time during the exercise motion when user U decreases the extension force upon ankle pads 74 user support 20 and user U move through a multi-dimensional articulating motion into a less elevated and less reclined position relative to stationary base frame 11 wherein a forward portion of user support 20 pivots about lower user support pivot 24A and a rearward portion of user support 20 pivots about upper user support pivot 24B causing movable slide support surfaces 14 to move in a downward arcing pivoting motion about movable slide support surface pivot assemblies 15 and slidable wedge 30 and slidable wedge to user support link bar 126 to move in a direction towards a forward portion of machine 10 which acts upon drive cable 41 which acts upon drive cable anchor mounting bracket 48 causing ankle pads 74 and a second end of ankle pad pivot bar 79 to move in a downward arcing motion towards seat pad 73 as a first end of ankle pad pivot bar 79 pivots about ankle pad bar pivot 87, causing user U to move from a more elevated and reclined position in the engaged and activated position to a more seat position in the at rest and inactivated position. Additionally when user U decreases the extension force upon ankle pads 74 at least a portion of weight stack plates 95 along with weight stack selector rod 96 and weight stack selector pin 97 concurrently move in a vertical downward motion guided by weight stack guide rods 94 this acts upon weight stack cable 46 which is attached at a first end to a forward portion of slidable wedge assembly 30 with a weight stack cable anchor 47 and attached at a second end to an upper first end of weight stack selector rod 96 with a weight stack cable anchor 47 such that slidable wedge assembly 30 is pulled in a forward direction with additional force equivalent to the additional resistance selected by user U to the exercise motion of machine 10.

[0072] User U can perform multiple repetitions of urging and releasing the force required to operate this embodiment of the machine 10 so as to perform a set of quadriceps muscle exercises. The multi-dimensional articulating motion of user support 20 in this embodiment creates a greater range of motion that more closely assimilates a natural extension and contracting motion of the user U's quadriceps muscles thus creating an improved and more effective way to exercise the user U's quadriceps muscles.

[0073] Features and components of the preferred embodiments of the present invention include at least one user support assembly 20 that cooperates with at least one movable upper body user engagement assembly 80A and or a lower body user engagement assembly 80B for exercising in a multi-dimensional articulating motion, the machine 10 comprising: (a) a stationary base frame 11 having a forward end and a rearward end that supports machine 10; (b) one or more stationary slide support surfaces 13 connected to or part of the base frame 11; (c) one or more movable slide support surfaces 14 pivotally connected at a rearward end only to a base frame cross brace 12; (d) a slidable wedge assembly 30 that simultaneously engages stationary slide support surfaces 13 and movable slide support surfaces 14; (e) a user support linkage assembly 25 comprising at least one user support link bar 126 that is pivotally mounted on a first end user support assembly 20 and pivotally connected on a second end to slidable wedge assembly 30 or base frame 11; (f) a user support 20 wherein a portion is pivotally mounted on at least one movable slide support surface 14 and a portion is pivotally mounted on a least one use support link bar 126; (g) a user engagement assembly 80A and or 80B with at least one attached receiver for receiving a user's hands or lower legs or torso; and (h) a drive linkage assembly 40 which consists of multiple components that operatively links the concurrent motion of the user engagement assembly 80A and or 80B to the user support 20.
