Anthony Sawyer Horton Jr. (born July 2, 1958), known professionally as Tony Horton, is an American personal trainer, author, and former actor. He is best known as the creator of the commercial home exercise regimen P90X.

Early life
Tony Horton was one of three children born in Westerly, Rhode Island to Anthony Sawyer Horton (Sr.) and Jean (née Gencarelli) Horton, and was raised in Trumbull, Connecticut. He has two sisters. His family is Roman Catholic. He was a self-described "98-pound weakling" with a speech impediment.

By the time he was 10 years old, his family had moved more than five times. His father served three years in the Army as a 1st Lieutenant, and the family was stationed at various bases around the U.S. His father was a minor league baseball player, golfer, and yachtsman. Tony Horton became interested in fitness when he took a weightlifting class while attending the University of Rhode Island and was a member of Phi Kappa Psi. After graduation, he moved to Southern California and worked various jobs, including as a stand-up comedian and gofer for 20th Century Fox.

Career
After moving to California in 1980, Horton became a personal trainer to an executive at 20th Century Fox, working out of his garage and charging $20 per lesson. His clientele grew, eventually including Bruce Springsteen, Usher, Tom Petty, Billy Idol and Annie Lennox.

He did some improv and worked as an actor. He appeared in the Thighmaster infomercial and a Shakeology commercial and as a spokesperson for NordicTrack. He starred in a number of exercise videos including Power 90. He later created a sequel, P90X—or Power 90 Extreme—which was his breakout hit. He went on to create variations of P90X, such as P90X2 and P90X3.

In 2017 Horton revealed that he was diagnosed with Ramsay Hunt syndrome.
