Abstract
The integral exercise device is made from a flexible plastic material and is designed to be rolled up into a compact unit when not in use. The exercise device includes a main body portion having apertures for receiving the user's feet or other body part, a connector portion that slides underneath a stationary object such as a door, and a shoulder portion that abuts one side of the door during use. The shoulder portion opposes the forces imposed by the user during exercising to maintain the user's feet in the desired position. The main body portion of the exerciser may be positioned by the user to any desired height. A fastener retains the exerciser in its rolled-up condition for easy transportation and storage.
