My wife had bought on the advice of her physiotherapist exercise bands for physiotherapy purposes for rehabilitation after an accident injury and has made excellent progress with the Dittmann tapes. Even after full recovery it will continue with the exercise program. I use the tapes also sometimes because they are a good tool to use for strengthening resilience. These exercises can weight exercises with dumbbells and the like. For this reason alone can not replace because of the movement mechanism and its elasticity are, after all the most important. ,
