Believe it or not, the best way to deal with the mind-melting ordeal of competing on a reality show might just be working out. Just ask Dylan Efron, a standout on Season 3 of the buzzy Peacock series The Traitors, who compares the experience of competing on the show with the feeling he gets at the tail end of a feat of endurance.

‘Training helped me in The Traitors mostly for my mental health—that game is a mind-fuck,’ Efron tells MH. ‘It’s that same feeling for me as the end of a triathlon, at the end of a marathon, where you’re telling yourself, ‘I’ve got to give up.”

Efron is prepared to push through those feelings of doubt, however, thanks to a rock-solid fitness foundation. He’s a bit of a thrill-seeker who has dabbled in rock-climbing, high-lining, and free-diving along with more traditional sports and endurance challenges like triathlons and Iron Man races.
