permitting the user to do a plurality of different exercises from different body positions includes foot support means which are vertically and horizontally adjustably spaced from rotatable body support means. ## Claims ### Claim 1 A device for selectively permitting the user to do sit-up and back extension and lateral extension exercises comprising a horizontal runner, a foot support assembly mounted to said horizontal runner, said foot support assembly comprising a first feet confining means for holding the user's feet generally stationary while the user's feet are disposed upwardly in the sit-up condition, a second feet confining means for holding the user's feet generally stationary while the user's feet are disposed downwardly in the back extension condition, a third feet confining means for holding the user's feet generally stationary while the user's feet are disposed in a sideways direction in the lateral extension condition, a pelvic support member mounted to said horizontal runner spaced from said foot support assembly, means for rotating said pelvic support member to one of a plurality of selected operative positions, said pelvic support member having a generally flat surface for supporting the user's pelvis in the sit-up condition to comprise one of said operative positions, said support member having a second surface for supporting the user's pelvis in the back extension condition to comprise another of said operative positions, said support member having a third surface for supporting the user's pelvis in the lateral extension condition to comprise a further of said operative positions, at least one of said second and said third surfaces being rounded, a pair of spaced upstanding projections extending outwardly away from said third surface to form a saddle in which the user's pelvis may be positioned for minimizing any tendency of the body of the user to twist or roll while providing support therefor, said saddle including means for accommodating different sized users, and said foot support assembly and said pelvic support member comprising the sole means for supporting the user's body whereby the user's body is thereby otherwise unsupported to maximize the degree of flexion and resistance and range of motion during the various exercises. ### Claim 2 (depends on 1) The device of claim 1 including indexing means for selectively locking said rotatable support member in one of a plurality of different positions. ### Claim 3 (depends on 1) The device of claim 1 including a brace on which said horizontal runner is mounted, said pelvic support means being secured to said brace, and said brace being inclined upwardly away from said foot support assembly. ### Claim 4 (depends on 1) The device of claim 1 wherein said spaced projections are padded to comprise said means for accommodating different sized users. ### Claim 5 (depends on 1) The device of claim 1 wherein said third feet confining means includes a vertically disposed rod means against which the user's feet may contact, and a generally vertical support surface rearwardly of said vertical rod means. ### Claim 6 (depends on 5) The device of claim 5 wherein said third feet confining means further includes a generally horizontally positioned support surface located above said vertical rod means. ### Claim 7 (depends on 6) The device of claim 6 wherein said third feet confining means further includes a generally horizontally positioned support surface located below said vertical rod means, said foot support assembly being laterally and vertically adjustable to be selectively moved up and down and toward and away from said pelvic support member, and said third surface of said pelvic support member being rounded. ### Claim 8 (depends on 1) The device of claim 1 wherein said first feet confining means comprises a set of generally horizontal rods against which the user's feet may contact, and support surface means rearwardly of said set of rods. ### Claim 9 (depends on 8) The device of claim 8 wherein said second feet confining means comprises two sets of generally horizontal rods against which the user's feet may contact, foot support surface means being rearwardly of said rods, and said second surface of said pelvic support member being rounded. ### Claim 10 (depends on 9) The device of claim 9 wherein said first feet confining means comprises one of said sets of generally horizontal rods and also said rearwardly disposed foot support surface means. ### Claim 11 (depends on 10) The device of claim 10 wherein said spaced projections are padded to comprise said means for accommodating different sized users, said third feet confining means including a vertically disposed rod means against which the user's feet may contact, a generally vertical support surface rearwardly of said vertical rod means, a generally horizontal positioned support surface located above said vertical rod means, a generally horizontal position support surface located below said vertical rod means, said foot support assembly being laterally and vertically adjustable to be selectively moved up and down and toward and away from said pelvic support member, and said third surface of said pelvic support member being rounded. ### Claim 12 (depends on 9) The device of claim 9 wherein one of said sets of rods is vertically adjustable and the other of said sets of rod members being angularly adjustable. ### Claim 13 A device for permitting the user to do a lateral extension exercise comprising a horizontal runner, a foot support assembly mounted to said horizontal runner, said foot support assembly comprising generally vertical rod means against which the user's feet may contact while the user's feet are disposed in a sideways direction, first foot support surface means rearwardly of said rod means, second foot support surface means disposed above said rod means, a pelvic support member mounted to said horizontal runner spaced from said foot support assembly, said pelvic support member being rounded in its upper pelvic contacting surface, a pair of upstanding projections extending outwardly away from said rounded pelvic support surface to comprise a saddle in which the user's pelvis may be positioned for minimizing any tendency of the body of the user to twist or roll while providing support therefor, said saddle including means for accommodating different sized users, and said foot support assembly and said pelvic support member comprising the sole means for supporting the user's body whereby the user's body is thereby otherwise unsupported to maximize the degree of flexion during the exercise. ### Claim 14 (depends on 13) The device of claim 13 wherein said projections are padded to comprise said means for accommodating different sized users. ### Claim 15 (depends on 14) The device of claim 14 wherein a generally horizontal support surface is located below said vertical rod means, and said foot support assembly being vertically and horizontally adjustable to be selectively moved up and down and toward and away from said pelvic support member. ### Claim 16 (depends on 14) The device of claim 14 wherein each projection includes a rigid member mounted to said support surface with the padding mounted thereon.
