Ryan Kwanten Likes Drunk Triathalons

It's not genetics. Or at least, it's not just genetics. Super-fit Ryan Kwanten spilled the specifics on his intense exercise habits.

"I've been known to turn up drunk at triathlons and do very well," the actor, 32, said in this month's Men's Heatlh. "I'm more of a heat-of-the-moment type of guy. A friend will tell me about something coming up, maybe that weekend, and usually not an abundance of thought goes into my doing it." Though he's known for playing Anna Paquin's brother Jason Stackhouse on the hit vampire show True Blood, Kwanten's background in his native Australia included a short stint as a professional triathlete.

The actor claims to work out for at least two and a half hours every day, although it's not just for the endless shirtless scenes he's made to do on the show. "I'm not one of those actors who gets physically fit for a role and then loses it all again. I'm very rarely in the gym," he said. "My workouts are predominantly outside, in nature."
