United Kingdom, April 5 -- Patrick Schwarzenegger's fitness is key to his mental health.

The 31-year-old actor worked out regularly while shooting the third season of 'The White Lotus' in Thailand, and Patrick has likened his workout plan to a form of "therapy".

The Hollywood star - who played Saxon Ratliff in season three of the hit HBO show - told E! News: "For me, running and working out is like my therapy - it's my alone time, my reset. It represents freedom - just being in my own space, my own zone.

"I don't necessarily have extremely specific goals unless they're tied to a character and how I want to look. For me, fitness is just as much about mental health as it is physical health."

Patrick enjoyed going on long runs in Thailan...
