A variety of selectively variable resistance exercise machines, of the type in which the exerciser is seated while grasping and forcibly moving a hand operable force input portion of the machine, are modified to permit their use by both able bodied and physically challenged, wheelchair-seated exercisers. To permit this alternate usage of the machines, each is provided with a movable, height adjustable seat structure which may be selectively pivoted between an able bodied exerciser use position, and a physically challenged exerciser use position. With the movable seat structure in this latter position, a wheelchair-confined exerciser may move the chair into the space previously occupied by the seat structure to thereby permit the exerciser to conveniently reach and operatively manipulate the machine\s force input portion. Differently sized floor ramp sets are provided to effect wheelchair height adjustment, and stabilizing straps are provided to releasably secure the exerciser and his wheelchair in an operative position relative to the machine. One of the machines has a unique “reverse pullover”input motion designed to simulate wheelchair ambulation motion to thereby strengthen the exerciser\s muscles used in forcibly rotating the wheels of the chair. Additionally, each of the machines may be provided with a specially designed double pin progressive resistance weight stack having differently sized weight elements and a central weight element connection rod which may be lifted and lowered by the physically challenged exerciser without moving any of the individual weight elements.

An exercise machine conveniently usable by both able bodied and wheelchair-seated exercisers, comprising: a support frame structure; force input means carried by said support frame structure, said force input means being hand engageable by an exerciser seated in an operative location relative thereto and forcibly movable by the exerciser relative to said support frame structure through a predetermined exercise motion; resistance means for resisting said exercise motion of said force input means with a yielding, selectively variable force, said support frame structure having a floor entry area along which a wheelchair may be rolled directly toward said force input means a distance sufficient to position an exerciser seated in the wheelchair in said operative location relative to said force input means; and seat means, including a seat member, carried by said support frame structure for movement relative thereto between first and second positions, said seat means in said first position being disposed within said entry area and operative to position an exerciser sitting on said seat member in said operative location, said seat means in said second position being essentially removed from said entry area to thereby permit a wheelchair - seated exerciser to unimpededly roll the wheelchair along said floor entry area, directly toward said force input means, to a position, adjacent said force input means, in which the wheelchair seat generally occupies the space vacated by said seat member and functions to position the wheelchair - seated exerciser in said operative location.
