You can find some of those in Dan and Dave's Trilogy, Dics 3. Difficult to describe the moves, and unrespectable for D&D. I reccomend to pick up the whole Trilogy, awesome piece of floushing and magic.
I agree with Doublem941 and get some PRO hand exercisers and get all 3. I also recommend Cando Digi-Extend Hand Exerciser it's awesome! You can get one from Amazon
Ah, my magical friends, I have a question. Do you really feel the difference before and after using these products? I always thought that this is kind of autosuggestion.
