If you’re getting ready to buy P90X — you may be wondering, “Who is Tony Horton?”

Tony Horton worked together with Beachbody to create several different popular fitness programs, including Great Body Guaranteed!, Power 90, Power Half Hour, 10 Minute Trainer, and the P90X DVD workout.

In addition, Tony is a personal fitness trainer in Santa Monica, California. He has also been the official spokesman for Nordic Track and his techniques have appeared in Men’s Fitness Magazine.

Tony met Carl Daikeler, the president of Beachbody, in 1996 and became his personal trainer. Their business partnership began after Carl experienced dramatic results thanks to Tony’s personal training plan.
