Claim Text:
1. An exercise machine, comprising: a frame having a first end and a second end; a platform movably positioned upon said frame, wherein said platform is adapted to be movable along an axis extending between said first end and said second end; a plurality of pulleys rotatably and fixedly supported upon said frame, wherein said plurality of pulleys are positioned side-by-side; and a plurality of tension devices each having a first connecting end attached to said frame and a second connecting end opposite of said first connecting end, wherein said second connecting end is adapted for selectively connecting to said platform; wherein said plurality of tension devices are each comprised of an elongated elastic object, wherein said plurality of tension devices are attached between said frame and said platform, wherein said plurality of tension devices jointly provide a resistance to movement of said platform in a first direction, wherein a level of said resistance is determined by the number of said plurality of tension devices operatively engaged with said platform, wherein said resistance is increased by operatively engaging additional tension units to said platform, wherein said plurality of tension devices stretch when said platform is moved in said first direction and wherein said plurality of tension devices contract when said platform is moved in a second direction that is opposite of said first direction, wherein as said platform moves in said first direction said level of said resistance is increased, and wherein said plurality of tension devices are wrapped around at least a portion of said plurality of pulleys.
