'Baywatch' star David Chokachi credits 3 a.m. wake-ups, twice-daily workouts for unbelievable physique at 58

David Chokachi is in the best shape of his life thanks, in part, to an unconventional routine.

Chokachi, 58, wanted to "make a statement" when he returned to the "Baywatch" set nearly 30 years after he first appeared on-screen as beloved lifeguard Cody Madison.

After climbing out of a dark place following an arduous recovery process due to Achilles tendon ruptures, Chokachi said that he "found a higher operating system" within, and became hyper-focused on optimizing his brain chemistry to benefit both mental and physical health.
