Abstract
An exercise apparatus provides a longitudinally oriented frame having a front end and a rear end, a seat carried on said frame in a forward facing position such that it is capable of carrying a user in a forward facing position with respect to the frame, a foot rest carried by the frame forward of the seat and adapted to receive, in use, the user's feet with legs in a generally forwardly extended position, a pair of hand engagable push/pull handles having one handle located on each of the right and left sides of said seat, each handle being carried by the frame for longitudinal movement approximately between at least the longitudinal positions of the seat and foot rest and for lateral movement approximately between at least a juxtaposed central position and a separated position, a variable resistance device employing a flywheel with centrifugal clutches for variably opposing forces applied longitudinally to the handles, and a diverting mechanism for laterally and yieldably redirecting a portion of forces applied longitudinally to the handles. The push/pull handles pass through a center of balance at an intermediate point of longitudinal travel and, when moving forward of such cente…
