My current day job is a data-entry slave. I suffer from OOS (occupational overuse syndrome) or RSI (repetitve stress injury) - typing all day then playing bass all night is not helping. Also playing live for longer lengths of time really burns me - I find I have to simplify some of my lines becuase my hands are so tired - tense and sore - I physically find it hard to press the strings down sometimes. Sounds awful and it is. I was wondering if anyone would like to share their warm-up routines/exercises for keeping their hands/wrists in good shape etc.
