The 25-year old Robert Pattinson has been hitting the gym lately, getting buffed under the guidance of Twilight co-star Kellan Lutz.

Kellan recently shared to MTV that he’s been helping Pattinson buff up for Twilight Saga: Breaking Dawn.

“I’m really proud of Rob for working out and really training really hard,” Kellan says. “He cycled so hard and trained very hard, and he’s really diligent. He talked to me about what proteins to drink and what to do and he listened and cared. He had great mentality for it.”

Kellan showed off his ripped body when he played a game of tennis at the Independence Day Weekend Party at Ciroc Cabna Club.

Breaking Dawn will show this November. I would love to see a shirtless Edward Cullen in a pair of shorts and running shoes side by side with team Jacob. I should be careful what I wish for because I just might get it!
