Jake Gyllenhaal: Prince of Persia Buff

A shirtless Jake Gyllenhaal shows off his buff body in these new stills from the upcoming fantasy adventure, Prince of Persia: Sands of Time.

“I over-prepared myself because I never knew how much they were going to ask me to do, so I just made sure I’d be hopefully able to do anything,” Jake has said of his new physique. “I guess I’ve gotten buff. There’s a lot acrobatics in the movie — a lot of running up walls, and jumping on things and Parkour, so it requires muscularity, but it requires a lot of aerobic ability too.”

Prince of Persia: Sands of Time opens in 2010.
