Hi guys: Aside of being a musician I'm into martial arts, weightlifting and some other sports. I've always heard that building BIG strenght in your hands is very good for sports, so I was thinking of fitting excercises of this kind into my daily routine. My question is: has anyone had bad experiences with too much hand strenght? May this end up in a loss of dexterity of my fingers? By the way I'm not talking about exercising with a Gripmaster or things like that but with heavy dumbbells. Thanks a lot.
