A stabilizer bar can hold the arms in spaced apart relation. In a preferred embodiment, the device is in the form of a truncated letter "A", having the stabilizer bar as the top horizontal segment of the letter, the arms as the two diverging sides and the strap as the inner horizontal segment. In use to assist abdominal exercise, the pad supports the head and neck, and the harness arms extend over the user's shoulders to avoid curling the shoulders. Extensions of the stabilizer bar can provide hand grips. One can also use the harness arms to support the torso in various exercises. The device can also be used to support the knee or leg in therapy.
