Anthony Sawyer "Tony" Horton (b. July 2, 1958, Westerly, RI, USA) is an American fitness instructor, probably best known for his development of the Power 90 Extreme ("P90X") home fitness system. Prior to his development of P90X, Horton developed the Power 90 ("P90") and Power Half Hour exercise programs, along with a variety of other workout programs. Both P90 and P90X are based on a 90 day workout regimen, and have their foundations in Joe Weider's bodybuilding routines.
