Created by J.B. Berns (a practicing martial artist for more than 20 years), the urban rebounding workout is a nonstop abdominal workout that melts away the fat and inches, strengthens your core and improves your balance and coordination like no other exercise. With this system, you can perform the urban rebounding workout in the comfort of your own home in just 20 minutes a day, three times per week. It brings the fun without causing pain or stress on your joints. That makes it especially ideal for athletes, seniors and anyone else who wants a low-impact, high-efficiency workout. Works all major muscle groups simultaneously, and combines numerous movements including abs, squats, lunges, push-ups and dips.
