Abstract

An exercise apparatus comprises a stationary support which supports a turntable platform for oscillating rotating motion. An arm exercising means in the form of a vertically disposed post is mounted forward of the perimeter of the platform. Responsive to oscillating rotating motion of the platform induced by a hip movement of the person standing on the platform, the post undergoes vertical reciprocating motion. Also, means are shown which, in addition to the motions described, cause the post to be driven in counter-rotation with the platform.
