Abstract: An exercise apparatus for performing a back extension exercise comprising: a frame, a seat having a seating surface and a pelvic stabilization pad having a lower back engagement surface, an input arm assembly interconnected by a first interconnection to a first resistance mechanism, the input arm assembly including a manually graspable mechanism and being arranged on the apparatus such that the input arm assembly is pivotable beginning from a start motionless position along a path of travel toward the pelvic stabilization pad under resistance exerted by one or both of the resistance mechanisms, wherein the first resistance mechanism is adapted to increase resistance as the degree of pivoting of the input arm assembly increases along the path of travel away from the start motionless position rearwardly toward the pelvic stabilization pad.

Abstract: A leg press exercise machine that provides translational and rotational motion of the user support structure by translating the user support structure along two intersecting non-orthogonal linear paths. A front portion of the user support structure travels along an inclining linear path and a rear portion of the user support structure travels along a declining linear path. The translation of the user support structure along the inclining and declining linear paths results in the user support structure exhibiting a rational motion, defining an arcuate path.
