The Thighmaster is an exercise product designed to shape one's thighs. The device is essentially two pieces of metal tube bent in a loop and connected with a hinge. The intended use is to put the Thighmaster between the knees and squeeze them together. This exercises the hip adductors. The simple mechanism allows exercising any suitable muscle where a small angle can be created to press it, for example the biceps (elbow flexion) or the hamstrings (knee flexion).
