This is a finger strength device I would advice it to anyone I was playing on the organ tonight and its was so easy to play. I have not been practicing as much because I have been on the site LOL but I have been exercising with this machine for the last week or so at work and while driving. You probably should not try it driving.

This is what it looks like.
http://www.gripmaster.net/gripmaster/ I got mine from walmart but I know you can get it from sports goods stores. I have the red medium tension. I may get the next one up soon. I will tell you all my progress in the next few months. But I was amazed at my finger speed. I recovered some that I lost years ago from not practicing.
