Abstract
An exercise apparatus comprises a stationary support which mounts a platform for oscillating rotating motion. Arm exercising means are mounted forward of the platform and are coupled to the platform to oscillatingly move toward and away from the platform responsive to oscillating rotational motion of the platform.
Claims5
An exercise apparatus comprising:
- a stationary support;
- a platform mounted upon said support for oscillating rotating motion about a centrally disposed axis and adapted to support a person in standing position;
- a pair of upstanding posts mounted forward of the perimeter of said platform and pivotally supported for enabling the upper end of each post to undergo oscillating motion in a direction generally toward and away from said platform, and
- means coupling said platform to said posts for causing the upper ends of said posts to move in opposition relative to each other toward and away from said platform responsive to oscillating motion imparted to said platform.

- a pair of upstanding posts mounted forward of the perimeter of said platform and pivotally supported for enabling the upper end of each post to undergo oscillating motion in a direction generally toward and away from said platform;
- coupling means which include a cross bar pivotally mounted substantially medially between its ends coupling said platform to said posts;
- the lower ends of said posts coupled to a respective end of said cross bar;
- means supporting said cross bar from said support, and
- drive means which include pulley and belt means coupling said cross bar to said platform to cause oscillating pivotal motion of said cross bar responsive to oscillating rotating motion of said platform for effecting the upper ends of said posts to move in opposition relative to each other toward and away from said platform.
