I don't know how many other people can type 120 wpm; I imagine there are a lot, but I just haven't ever met any. As a programmer and a guitarist, being able to work quickly and efficiently with my hands is important to me. That's why these videos demonstrating actual hand exercises are pretty cool.
Besides strengthing the hand, improving dexterity, coordination, and preventing carpel tunnel syndrome, these double as great party tricks. Check it out!
Greg Irwin is a guy from Miami University in Oxford, Ohio who decided to develop his ability to play EVERY instrument. He realized three special skills were required: auditory (the capability of the ear), mental (the ability to process rhythms, harmony, and melody), and physical (strength, dexterity, and coordination).
The first two were agressively trained in formal coursework. However, the physical skill was noticably absent.
After talking to hand surgeons, physical and occupational therapists, as well as sports medicine professionals, Greg found that, although there were programs for rehabilitation for the hand, there were none for advancing the ordinary hand to a higher level of strength and coordination. So, Greg developed his own exercises.
That was in 1980. Since then Greg has has developed several products and programs to increase the strength, coordination, and dexterity of your hands and fingers. He also has some pretty fun video clips from his TV appearances on Johnny Carson, Jay Leno, and others.http://www.handhealth.com/video-warmups
