Booboo Stewart’s Shirtless Martial Arts Workout [PHOTOS]

Twilight hottie Booboo Stewart definitely knows how to stay in shape.

Yesterday (July 9, 2012) Booboo practiced his martial arts moves shirtless while going for a run in Los Angeles. BooBoo, 18, became a Martial Arts World Champion at the age of eight.

Recently TakePart TV chatted with Booboo and Twilight’s Mike Welch, who spoke exclusively about summer plans, current and upcoming projects and something near and dear to their hearts — helping the world’s water crisis through the Thirst Project.

The Thirst Project is a nonprofit committed to solving the world’s water crisis. About a billion people on the planet don’t have access to clean drinking water, and 4,400 children die every day from diseases caused by contaminated water. That’s approximately one child every 15 seconds. TakePart and the Thirst Project are looking to change that.

Check out what Booboo and Mike have to say below, then check out Booboo in action by launching the gallery.
