Finger Fitness Dyna-Flex Power Ball (Standard)

If you're a guitar player and have a bad case of Popeye Arm from rehearsing too much, your wrist feels tight, you fingers are tense, etc. I highly recommend using the Power Ball. It eliminates tension in all these areas when used moderately several times during the day. It will also build up strength in any of the areas you work out. Just don't drop it on the floor or it will crack. The string can be improved by fixing a small piece of masking tape on the tip to give it strength. Any sports medecine or therapy center should have these, they truly work.

Excelente

Not my type of practicing, may be good for somebody else. Too much to do with two hands. I prefer hand exercisers, you can walk or watch tv and do it, this thing needs attention.

Unfortunately I never use...difficult for me to get going. Will keep on trying.

Pretty amazing.

I'm an avid guitarist and gamer couch-potato. The result is a sore elbow and the potential for carpal tunnel. I've been using it for a couple of days and am feeling a serious burn in some muscles I don't use much. I'm hopeful about the long term benefits. It's a work out.
