ABSTRACT:
An exerciser device comprises an elastic compression body which is configured to accommodate a wide variety of exercises for different muscle groups and enclosed within the body is a flexible reservoir of liquid communicating with a transparent gauge tube disposed at the surface of the body for viewing the liquid level therein by the person using the exerciser. The end of the gauge tube opposite the reservoir communicates with an air compression chamber in which compressed air resiliently opposes movement of the liquid in the gauge tube in response to compression of the elastic body.
