Without the will goes in sport nothing. But who feels like to train, will have his fun with this toy. You can use it very effectively train in a short time. Straight shoulder arm and upper back muscles can be very good austrainieren (eg with the verscheidenen rowing exercises). Use it almost daily for 2 weeks, and have a clear (even visible) power growth. Level 3 is already getting too easy, have therefore already ordered my Level 4. So you can then use verscheiden strong ligaments also depending on the muscle group. In my opinion is also for Biceps / Triceps effktiver as dumbbells by the dynamics of rubber bands. Plus pushups, AB-Roller for the abdominal muscles and a Powerball for forearms .... gym? Waste of money!
