Abstract
The exerciser is adapted to simulate the motions and conditions incident to making turns on a ski slope, and for perfecting body movements that are important for the safety of skiers on a snow-covered slope. The exerciser has a platform for supporting a person and a support including a frame for supporting the platform for rotation in accordance with shift of weight and movements of the person. Restraining spring is coupled between the platform and the frame. The spring is effective to yieldably resist with increasing force the increasing tendency of the platform to rotate clockwise or counter-clockwise from a neutral position relative to the frame.
