The Wunda chair (in German – Wunda means wonder) is a powerful piece of equipment that was designed by Joseph Pilates as a portable home exercise machine. Joseph Pilates used the chair to rehabilitate lower body injuries as well as challenging advanced students with more aerobic, full body exercises. While some exercises are performed sitting on the top and pressing the pedal down, other exercises can be done lying on the floor, standing up, hands on the pedals and standing on the seat among other positions, so don’t mistaken the name, Pilates chair – there is much more to it than a sit-down workout.
