Hands can hurt and tingle at the end of a long day's work.
And if you start thinking of yourself as an athlete, then all the notions of warming up and stretching and conditioning make sense. People's biggest problems with their hands come from overuse and not warming up their hands properly. Regular stretching, toning and conditioning of hand muscles can prevent pain, aches and disabling hand injuries. See Irwin's Web site for some finger fitness demos for 'finger face' and 'finger folds'. Many products are available for hand exercising, but you can use a small rubber ball.
