As we all know, good grip is essential in climbing. Kletterretter PowerFingers help strengthen the forearms, wrists and fingers. The set consists of five elastic drive discs of different strengths. Depending on the intensity, the choice will be made on a single or on a combination of several discs. Whether for warm-up, for a short bodybuilding session from time to time or for rehabilitation, this system offers up to 125 combinations. The extensors, in particular, are worked and the opposing muscles are balanced. Training discs can also help with typical climbing problems, such as epicondylitis. Kletterretter's PowerFingers give the project the last push!
