Abstract: An inexpensive, light-weight, easy to use exercise device which is comprised of a harness having an adjustable flexible, inelastic strap with and adjustable foot loop at one end and a hand grip at the other end. Most exercises are performed using two exercise harnesses. While holding the hand grips and having placed the feet in the foot loops, the user exerts opposing forces between the arms and legs in a variety of exercises while lying down, standing, or sitting. By varying the strength of the forces exerted and the speed of the motion, the user can do isometric, isotonic, stretching, or aerobic exercises.
