Get him an ipod Nano; then get him a neckace to wear it around his neck so it won't be in the way while he works out. He may just clip it to his shirt - it's so small I don't even know it's there. I clip mine to my shirt tail when I'm mowing the yard and let the earbud wires drop down my back. It has a built-in radio, and you (or your kids) can introduce him to the world of digital music and iTunes. Working out is better with you own music.
