Joe Rogan began training at age 13 and earned his black belt in 2 years.
He won the US Open Taekwondo Tournament at age 19, as a lightweight.

Rogan has spoken about his Taekwondo competitions, even revealing a "dark truth" about knocking out opponents, an aspect of fighting he doesn't feel good about.
