ABSTRACT:
This invention relates to a portable exercise device for resistance type exercises of all muscles which make up the buttocks, including the gluteus maximus, gluteus minimis, gluteus medius and the piriformis muscles by both hip extension and hip abduction without undue stress on the spine and corresponding musculature. The device has a generally horizontal extending base, a headrest affixed to the base, a resistance bar for pressing against the underside of the thigh of the user which is pivotal to the base. Biasing means is provided for urging the resistance bar to a vertical position with a force which the user can overcome by moving the leg and thigh downward and for moving the resistance bar to a horizontal position. Biasing means is also provided for exerting a force to resist outward movement.
