Talking with the magazine about his approach to working out, Hunnam explains, “I get more out of fitness mentally than I do physically. It’s like an oil change. Your body is mostly water and it gets dirty, you know? You have to clear the dirty water otherwise it’ll corrupt everything; your thoughts, emotional process and body. I get addicted to the endorphin release of working out – my whole physiology relies on that. If I get injured or I don’t have time, I’ll start to feel cloudy, then depressed.”
