the gripmaster topic

i hope this applies to this forum; if not, sorry. the last few months ive really been interested in ways to warm up easier than grabbing a guitar on distortion in the morning. ive looked into the gripmaster a little bit, and ive heard good feedback (obviously, its just a damn springboard for excersising your fingers) but ive heard stuff about carpal tunnel aggrivation too. i understand that guitar in itself aggrivates wrist pain, but is there anything to look out for when using finger workout tools like that? anyone that uses/has used them, why did you stop using them, ect. any feedback. im a pussy, and i remember pulling a tendon in my wrist which basically put me out of playing guitar for over a week, which was hell. feedback!

I messed up my fretting hand big-time a couple of years ago and I used the Gripmasters for my rehab.[/font]

I used a DynaFlex ball after I broke my wrist.

It's basically a weird looking ball with another ball inside it.
You use a string to get the inside ball spinning and then use your wrist to keep it going. Centrifugal force keeps it moving and it really works the fingers and wrist muscles. .. like so much that it hurts if you overdo it.

thats crazy...haha
