I've seen the Flexibar earlier and thought to myself, what's the point. Anyway, I had recently physiotherapy - Muscle Building Exercises. Since my Flexibar for home was advised to buy. In the beginning you think that does nothing. But after 10 minutes, you realize that you are doing something. What is important, but that's for each device so that you have to alternate with the exercises, so that the fun remains. In alternating exercises you realize how the entire body must work together to get shut the bar to vibrate and the next day you notice the muscles that you do not move otherwise. So you get a different body sensation. Inflate to the muscle, it is certainly not appropriate, there must already correctly iron ago, but if you want to do something for the entire body, it is certainly not a bad buy. Although it is more expensive than at discounters, the rod is better in the hand.
