Anthony (Tony) Sawyer Horton is commonly known as "America's Trainer" because he is the most well-known and recognizable male personal trainer in the USA. He is a personal trainer, creator of many exercise video series, several books, former stand-up comedian, infomercial actor, and movie actor. He moved from the East Coast to California at a young age, and while trying to break into acting, other actors noticed how fit he was, and hired them to train him, including Tom Petty. He was instrumental in changing the genre of exercise videos from being produced as a low-budget cheesy afterthought into professionally produced, high-quality content. His most famous, revolutionary exercise program is P90X. It was followed by P90X2 and P90X3. In 2017 Tony revealed he was diagnosed with Ramsay Hunt Syndrome. But after a 2 year break, he came out with his latest series, called "Tony Horton's Next Level". In 2014 Tony married Shawna Brannon, who also appears in P90X3. They live in the greater Los Angeles area. Tony is now in his 60's and still going strong - active on Facebook other social media and in public life, conducting regular interviews to help Americans stay in shape.
