Abstract: An exercise device for martial arts conditioning including a belt having rings, a torso harness a hand stirrup for each hand, a knee band for each knee, and an ankle band for each ankle. The harness includes front and back straps and is attached to the belt in the front and the back. A loop is attached on the harness at each shoulder for receiving an elastic cord. At least two more loops are attached to the back strap to receive elastic cords. Specialized channels in the knee band are adapted to receive elastic cords that are attached to the belt and the ankle. A method of use for practicing punching and blocking motions includes passing an elastic cord through the loops on the back harness strap, grasping each end of the cord with either hand, and repeatedly punching and blocking. A method of use for practicing kicking includes attaching elastic bands to the belt, passing them through the specialized channels on the knee band, attaching the cords at the ankle, and repeatedly kicking.
