The Xiser Machine™ was engineered to ensure correct hip and knee alignment, providing an optimal, impact free workout. The hands-free design promotes the development of stabilizer muscles and correct posture, thus improving balance. Stepping on the Xiser is like doing multiple one-legged squats on both legs at the same time. This creates a great demand on the muscles because there is no rest period for the muscles during stepping. This type of exercise (Burst Training) challenges both aerobic and anaerobic systems at the same time. That is why the Xiser can produce such a wide range of benefits in as little as 12 minutes per week and is safe and effective for everybody.
