Abstract
Abstract A machine for exercising the human body muscle system has a platform on which the user rests and which is mounted to swivel about a vertical pivot and at the same time to rock or ''''seesaw'''' about a central horizontal pivot. The swiveling friction is controlled to some extent by bearing collars. The rocking action is resisted by springs. The rocking load may be increased by attaching weights to the platform. A handle-bar support is provided in position to be grasped by a user standing on the platform. Parallel handrails on opposite sides of the platform are adjustable to various positions.
