Abstract
Abstract With the device belted around the waist and the user in either a standing or lying down position, the device is ready to be used. The leg restrainer #25 is, depending on the height of the individual, just above the knees. The stomach pad #3 is just below the waist and the chest pad #2 extends from the solar plexus up. The handles are a little below shoulder height and about shoulder width. When the device is being used resistence comes from the pressure between moving the leg restrainer and the chest pad and handles #6 and #7. When the opposite ends of the device are moved a large force is pushed inward at the joint wherein the stomach pad was placed. To keep the device locked so that it will not extend backwards past the vertical, the ends of tubes A and B meet in front of stomach pad #3 and behind the joint.

Claim 1
Independent Claim
174 words
An abdominal exercise device comprising two oppositely extending elongated structural member means; the opposing ends of said structural member means being pivotally joined to pivotal resistance means tending to pivot and hold said elongated structural member means in substantially the same plane; the free ends of said elongated structural member means each having a body contact member means attached thereto, with a third body contact member means attached to one of the elongated structural member means adjacent the pivotal resistance means and overlying the opposed ends with all said body contact member means lying in substantially the same plane; said third body contact member means having means for fastening said third body contact member means to the waist of an operator whereby, with the third body contact member means at the abdomen of the operator and the other two body contact member means at the chest and thighs respectively, the operator can do abdominal exercises, sit-ups, and leg lifts by pivoting the elongated structural member means against the opposition of the pivotal resistance means.
