(CNBC) — Tony Horton is happy to tell anyone who will listen that he's turning 59 next month.
The creator of such popular workout programs as the P90X (and P90X2 and P90X3) and 22 Minute Hard Corps, Horton found his success by telling others that they don't need to be perfect.
No question, his workouts are hard, in some cases extreme, but there is always a modification and never an expectation of perfection. The idea is to work toward success on a regular basis, something he practices himself, even as he approaches his 60s. His mantra: "Do your best, forget the rest."
