I often suffered from pain under my right shoulder. I would say after maybe one hour of practising. I tried everything. Gymnastics, physiotherapy, relaxation exercises while practising and afterwards too. All of this still led to unsatisfactory results. But since I’ve been practising on the kyBounder, I always stand on it and then get off and walk around a little bit. I don’t suffer from the pain any more. It’s incredible.
