I have been thinking about this for the past few years and decided to get some feedback from all of you in TB land. I am a 43 year old bass player with 23 years experience. Lately no matter how much I ignor it when I play for long periods of times my hands, arms, and forearms hurt. When I say hurt I don't mean unbearable pain, but I feel it. I was wondering what other guys do as far as warm ups, excercises, and vitamin supplements. I know there are thousands of other players in this age group, or younger, and just want some ideas.
