This AeroPilates Level Two Simply Cardio Workout DVD is designed for use with an AeroPilates reformer with a rebounder (sold separately) and is the resource you need for a total body, cardio-focused workout. 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 rebounder exercise, making this one of the most effective low-impact workouts on the market. Your spine, hips, ankles, knees and feet are completely protected from stress because you rebound while lying down. Increase your range of motion, flexibility, strength and cardiovascular fitness while increasing your metabolism and losing weight. This Pilates DVD is about 16 minutes long and can be completed twice for a longer workout, making it easy to fit health and fitness into a busy life!
