with reference to fig1 - 3 , an embodiment of an inclinable exercise device 100 includes an adjustable , pivotal , tiltable user support platform 105 . before describing the pivotal user support platform 105 , the inclinable exercise device 100 will be generally described . the inclinable exercise device 100 includes a vertical support member or tower 110 having a base 120 and a tower housing 130 . the base 120 includes a pair of opposite foot - shaped base members 140 joined by an intermediate base section 150 . the tower housing 130 extends from the intermediate base section 150 of the base 120 . the tower housing 130 includes a motorized lift mechanism to lift and lower ( and adjust the angle of ) the collapsible exercise device 100 . in alternative embodiments , the collapsible exercise device 100 includes a non - motorized lift assist mechanism or no lift assist mechanism for assisting the user in adjusting the angle / inclination of the collapsible exercise device 100 . a pair of upper rails 250 are connected to lower rails 240 . a strut ( or struts_ 260 is / are pivotally connected to the base 120 and is also pivotally connected to the rails 250 , 240 at rail pivot points 230 . the rails 250 , 240 support the slidable / movable pivotal user support platform 105 . a folding squat platform 360 is shown in an unfolded state . the folding squat platform 360 includes opposite parallel rails 370 joined by perpendicularly extending cross rail 380 . a pivot portion 390 carries a spring - loaded pull pin 410 for locking the folding squat platform 360 within a pin hole near a distal end of the lower rails 240 . folding , combination pulley - support and pull - up bars 830 are respectively pivotally connected to mounting mechanisms 385 at proximal ends 220 of the upper rails 250 . the mounting mechanisms 385 move up and down with the motorized lifting mechanism for raising and lowering the rails 240 , 250 . each bar 830 has a trapezoidal configuration . for normal use , the bars 830 may be moved to the position shown in fig1 - 6 . for performing chin ups and related exercises , the bars 830 may be moved to a position where the bars 830 are generally parallel with the rails 240 , 250 . pulleys 940 are slidably attached to the bars 830 . an exerciser may move each pulley 940 to a desired position on the bar 830 . a connector extends through the pulleys 940 and connects to the pivotal user support platform 105 . the connector may be of any suitable well - known type , but is preferably a cable . the cable includes handles ( connected via links ) at each end and extends through the pulleys 940 positioned on the combination pulley - support and pull - up bars 830 and loops through a third pulley attached to the pivotal user support platform 105 . the third pulley is positioned along the lateral centerline of the pivotal user support platform 105 . this position allows for unilateral ( i . e . one arm ), bilateral ( i . e ., two arm ) and static equilibrium ( i . e . holding the pivotal user support platform 105 suspended by keeping a constant force on each handle ) use . the cable should preferably be of sufficient length to extend through the pulleys 940 and allow the exerciser to grasp one or both of the handles while the exerciser is on the pivotal user support platform 105 and the pivotal user support platform 105 is at rest . in an alternate embodiment , the connector may be two separate cables extending through the pulleys 940 with each cable fixedly attached to the pivotal user support platform 105 . with reference to fig9 , the pivotal user support platform 105 will now be described in more detail . the pivotal user support platform 105 includes a support frame 350 and a glide board / support platform frame 351 pivotally connected to the support frame 350 at adjacent ends via a pivot mechanism . the pivot mechanism includes pivot pins 352 disposed through holes in the adjacent ends of the support frame 350 and the glide board frame 351 . the support frame 350 includes elongated parallel longitudinal rails 353 , and a pair of transverse rails 354 ( one of which includes hook member 361 ) connecting the longitudinal rails 353 . near opposite ends of the longitudinal rails 353 , rollers 355 are provided for rolling movement of the pivotal user support platform 105 on the rails 240 , 250 . along an inner side of the transverse rails 353 , a notched groove 356 with multiple support notches 357 are disposed . with reference to fig1 , the glideboard frame 351 includes elongated parallel longitudinal rails 358 , and upper brackets 362 and a lateral bracket 363 attached to the elongated parallel longitudinal rails 358 . a tilt angle adjustment mechanism in the form of a retractable support mechanism 344 is pivotally attached to the elongated parallel longitudinal rails 358 and the lateral bracket 363 . with reference to fig9 , the retractable support mechanism 344 includes parallel support rails 364 connected at an end by a support bar 365 . the support rails 364 are pivotally connected to the elongated parallel longitudinal rails 358 and the lateral bracket 363 via pivot pins 359 . a main support pad / support platform 366 is attached to and supported by the glideboard / support platform frame 351 . a bumper ( not shown ) may be positioned on the lower rails 240 to prevent the pivotal user support platform 105 from rolling all the way down the lower rails 240 . in use , the exerciser positions himself or herself on the pivotal user support platform 105 and grasps one or both of the handles . the exerciser then draws one or both of the handles toward the exerciser and by doing so transports the pivotal user support platform 105 up along the lower rails 240 and upper rails 250 . using the motorized lift mechanism , the height of the proximal ends 220 of the upper rails 250 ( via the mounting mechanisms 385 ) are raised and lowered , varying the angle of inclination of the rails 250 , 240 . the adjustment of this angle of inclination alters the percentage of the exerciser &# 39 ; s weight which the exerciser &# 39 ; s muscles are moving . this allows for adjustment of the intensity of the exerciser &# 39 ; s workout . an exerciser may also vary the resistance while working upper body muscles by positioning him or herself on the pivotal user support platform 105 with the exerciser &# 39 ; s feet on the squat stand 350 or floor . the legs and lower body then provide assistance in moving the pivotal user support platform 105 , lessening the load on the upper body muscles . the exerciser may also use the squat stand 360 to perform the squat exercise for the lower body muscles . the exerciser may adjust / move the tilt angle of the pivotal / tiltable user support platform 105 by pivoting / tilting the glideboard frame 351 and the main support pad 366 ( about pivot pins 352 ) relative to the support frame 350 . the angle of the glideboard frame 351 and the main support pad 366 relative to the support frame 350 is locked into place at the desired tilt angle using the retractable support mechanism 344 ( the support bar 365 is set in the appropriate notches 357 ). setting the support bar 365 in the different notches 357 allows for 4 , 8 , 10 , 12 , 14 , and 16 degrees of tilt relative to the support frame 350 . with the glideboard frame 351 and the main support pad 366 pivoted upwards relative to the support frame 350 , the retractable support mechanism 344 at the bottom / lower end of pivotal user support platform 105 is pivoted / moved between a “ normal ” retracted orientation ( where a plane defined by the glideboard frame 351 and a plane defined by the support frame 350 are substantially parallel and substantially coplanar and the support bar 365 is fully disposed inwardly , toward center of glideboard frame 351 ( in the notched groove 356 ) to a “ supported ” position ( fig1 , 12 ) where the glideboard frame 351 and the main support pad 366 are supported at an angled orientation relative to the support frame 350 ( the support bar 365 is set in the appropriate notches 357 ). to return the pivotal user support platform 105 to the “ normal ” retracted orientation , the glideboard frame 351 and the main support pad 366 are pivoted upwards relative to the support frame 350 ( so that the support bar 365 is no longer engaged / locked in the notches 357 ), and the retractable support mechanism 344 at the bottom / lower end of pivotal user support platform 105 is pivoted / moved from the “ supported ” position , where the support bar 365 is engaged / locked in the notches 357 , to the “ retracted ” position ( where the support bar 365 is fully disposed inwardly , toward center of glideboard frame 351 , in the notched groove 356 ). the glideboard frame 351 and the main support pad 366 are then pivoted / lowered to a “ normal ” orientation , where the glideboard frame 351 and the support frame 350 are substantially parallel and substantially coplanar . in an alternative embodiment , the notches 357 are disposed in the glideboard frame 351 and the retractable support mechanism 344 is pivotally coupled to the end of the support frame 350 , enabling the pivotal user support platform 105 to work in a similar , but opposite , manner compared to that described above . the pivotal user support platform 105 allows the exerciser to maintain neutral spine position and proper posture , which is important during rotating exercises . the pivotal user support platform 105 makes it easier for the exerciser to maintain correct posture during certain exercises , achieving a safer and more functional result . for neurological patients , the pivotal user support platform 105 allows them to sit on a horizontal carriage while relearning motor skills , training the proprioceptors and gaining increased proprioceptive response , needed for stability and agility . for patients rehabilitating from a stroke , the pivotal user support platform 105 also makes is easier for them to get on and off the exercise device . with reference to fig1 - 16 , an alternative embodiment of a pivotal user support platform 505 that provides infinite tilt adjustment ( i . e ., infinite tilt angles ) between 0 degrees and 18 degrees will be described . the infinite adjustment pivotal user support platform 505 includes a tilt angle adjustment mechanism in the form of a screw - type tilt angle adjustment mechanism 510 . the screw - type tilt angle adjustment mechanism 510 includes a screw block 520 with a threaded interior bore that threadably receives an externally threaded screw shaft 525 . a proximal portion of the screw shaft 525 is rotatably disposed in a hole of transverse rail 359 a , and the screw shaft 525 is in the same plane as a plane defined by support frame 350 a ( and parallel with longitudinal rails 353 a of the support frame 350 a ). a proximal end of the screw shaft 525 includes a hand crank 530 . in an alternative embodiment , the tilt angle adjustment mechanism 510 includes a remote - controlled motorized screw - type tilt angle adjustment mechanism instead of a manually controlled screw - type tilt angle adjustment mechanism . support bar 365 a extends laterally through another bore in the screw block 520 and is connected to a bottom of retractable support mechanism 344 a . opposite ends of the support bar 365 a are slidably and guidably disposed in smooth guide groove 356 a . in an alternative embodiment , the screw - type tilt angle adjustment mechanism 510 and the groove 356 a are substantially disposed in the glide board frame 351 a instead of the support frame 350 a , enabling the pivotal user support platform 505 to work in a similar , but opposite , manner compared to that described above . in use , an exerciser adjusts the tilt angle of the glide board frame 351 a and the main support pad 366 a relative to the support frame 350 a by operating the screw - type tilt angle adjustment mechanism 510 . clockwise and counter - clockwise rotation of the externally threaded screw shaft 525 via the hand crank 530 causes the screw block 520 to move forward or rearward relative to the longitudinal direction of the support frame 350 a . this causes the bottom of the retractable support mechanism 344 a to also move forward or rearward with the ends of the support bar 365 a being guidably disposed in the guide groove 356 a . as the bottom of the retractable support mechanism 344 a moves longitudinally relative to the support frame 350 a , the top of the retractable support mechanism 344 a ( along with the coupled end portions of the glide board frame 351 a and the main support pad 366 a ) moves towards or away the support frame 350 a , changing the tilt angle of the glide board frame 351 a and the main support pad 366 a relative to the support frame 350 a . the tilt angle of the glide board frame 351 a and the main support pad 366 a relative to the support frame 350 a can be set in an infinite number of tilt angles between a maximum tilt angle ( e . g ., 18 degrees , fig1 ) and a minimum tilt angle ( e . g ., 0 degrees , fig1 ), where the glide board frame 351 a and the support frame 350 a are substantially parallel and substantially coplanar . the infinite adjustment pivotal user support platform 505 provides the exerciser with greater control of tilt angle adjustment than the pivotal user support platform 105 . although the pivotal user support platforms 105 , 505 have been described as being tiltable between angles of 0 degrees and as much as 18 degrees , in alternative embodiments , the pivotal user support platforms 105 , 505 are tiltable between one or more alternative parameters ( i . e ., greater and / or less than those indicated ). further , in alternative embodiments , the tilt angle adjustment mechanism includes a different configuration that those described / shown herein . the above figures may depict exemplary configurations for the invention , which is done to aid in understanding the features and functionality that can be included in the
