One of the things I heard this last interview cycle from dental students was that I should start working on my wrist strength. I had never even thought about doing such a thing. So, last night, I went to the local sporting goods store and bought one of these gyro-scope balls. I can already feel some results (i.e. a very tired arm, wrist, and hand). Another benefit is that it has a lower chance of causing carpal tunnel syndrome then the other alternatives. Are any of you doing something to improve your wrist strength?
