Burn calories while protecting your body from strain and stress! The AeroPilates Free-Form Rebounder is designed for use with the Stamina 55-4286 AeroPilates Reformer (sold separately). While Pilates is exceptional for improving strength and flexibility, cardio is the third component necessary for complete health and fitness. AeroPilates reformers solve this problem by combining Pilates exercises with aerobic free-form rebounder exercises, making this one of the most effective low-impact workouts on the market. In fact, you can maintain a heart rate just as effectively as on a treadmill, but without the stress on your spine, hips, ankles, knees and feet, which are protected because you exercise while lying down. This trampoline rebounder is simple to interchange with the footbar on your rebounder Pilates equipment. The set includes a 20-minute workout DVD from Pilates expert Marjolein Brugman.
