An exerciser comprising: a frame assembly including a track; a movable body support disposed on said track and constructed and arranged to support the body of an exercising person in a position which allows the body of the exercising person to move with the movable body support while enabling the feet of the exercising person to be free to be moved with respect to said movable body support; and a movable foot support coupled to said frame assembly and constructed and arranged to be engaged by the feet of the exercising person supported on said movable body support, said movable body support being mounted on said track for movement in a first direction away from said movable foot support and in a second direction toward said movable foot support; and said movable foot support having resilient structure capable of providing a spring force in response to the engagement of the feet of the exercising person moving with the movable body support in said second direction and to establish, as a result of the spring force, a return movement by the movable foot support in said first direction which can be translated by the exercising person into a movement of said movable body support in said first direction; wherein movement of the movable body support relative to the track is restricted to linear translational movement.
