Abstract

Abstract An exercise device for developing skiers'' leg muscles which are used when skiing in the so-called ''''sitting'''' position. The device includes a pair of simulated skis having their front ends resting on the floor and their rear ends supported in an elevated position from a chair for movement from side to side as well as up and down against the resistance of an opposing yieldable force or a periodic positive elevating force. The user sits in the chain or stands with his feet positioned in foot receptacles on the skis and moves his legs and feet in a twisting and/or up and down motion to move the rear ski ends from side to side and/or up and down against the resistance of the opposing force.
