ABSTRACT:
A resistance exercise apparatus is provided which comprises generally means for receiving a body extremity of a user, the means for receiving a body extremity subject to a force provided by the body extremity, this force resulting in limited movement of the means for receiving a body extremity; means for maintaining the means for receiving a body extremity in a predefined plane during movement; and a means for providing resistance to movement upon application of the force to the means for receiving a body extremity. The apparatus may include a self supporting base portion, or may be adaptable for temporary connection for a bed. This apparatus, both portable and stationery versions, combines the well-known resistance methods of isometrics and isotonics to provide a more efficient exercise. Resistance is provide within a single plane by an elastic cord or by a fluid device.
