| I also found with the powerballs that if affects your grip after a while. I found my fingers were not as strong as they used to be and found pain in my finger joints. I am only 23 by the way and a musician playing saxophone and guitar so have strong nimble fingers anyway, this affected my playing and general pain occured.
Don't get disheartened, use it and enjoy it, just stop when it starts to hurt. Dont go all macho and keep going. |
