C.J. Senter may or may not be the next Tony Horton or the next Barry Sanders, but he is definitely the next 10-year-old to watch.

Granted, when most people hear "child prodigy," they rightfully raise an eyebrow and wonder who is pulling the strings. Add a workout DVD by a fourth-grader with sculpted muscles to the mix and "cute" can turn to "concerning." But it turns out the story behind "C.J. The Workout Kid" is a lot more inspiring than insidious.

C.J. started working out five years ago when his football coach told him and his teammates to go home over a weekend and get some exercise. He did some push-ups and sit-ups and loved it. Not too long after, he saw a P90X infomercial and loved that too. He's been working out ever since. C.J. does his own routines three times a week, after school and homework, and he's given new names to some old and boring moves, like the burpee, which involves a squat, push-up, and jump. C.J. calls that one the "shredder." He even teaches a class of (mostly older) kids at the gym near where he lives in Locust Grove, Ga.
