Most equipment designs utilize a spring mechanism that the exerciser works to control while moving in various planes. The idea to use springs was conceived while Joseph Pilates was interned during WWI. He attached bed and machinery springs to the bedposts of infirm prisoners. With the arrangement, he facilitated circulation and healing by moving injured limbs in ranges patients could not otherwise perform, thereby restoring joint function and muscular strength and re-educating the body.
