ABSTRACT:
An exercise device has a foot platform supported on tracks in a frame for linear lateral movement, the movement of the platform being frictionally damped, as by a tensioned belt. The platform is tilted forward to constrain a user standing on the platform, and holding on to hand grips supported by an upwardly extending frame portion forwardly of the user, to assume an anticipation position with knees bent. The upward extending portion of the frame also has rearwardly extending bars to either side of the user's waist to restrict lateral body movement as the user projects the foot platform from side to side by leg movements. The platform movement is controlled by parallel links extending from the platform, parallel to the user's legs as seen from the front, and through pivotal connections to the upper part of the frame, the movement of the links through the pivots being controlled by springs and stops both so as to bias the platform towards a central position and so as to limit its outward travel along the tracks.
