Mystery solved: Find out what Rob did to get in shape for his ‘Breaking Dawn’ sex scene!
When we first saw Robert Pattinson‘s surprisingly muscular back in the Breaking Dawn teaser trailer, we had to wonder if he used a body double for the big sex scene with Kristen Stewart. Not so, says Kellan Lutz! Rob’s on-screen brother comes to his defense in a new interview, adding he’s “really proud of Rob for working out and really training really hard.”
“Someone asked if that was me,” Kellan says in an interview with MTV News. “[Rob] 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 a great mentality for it.”
We’re glad this issue has finally been cleared up — and that Kellan is so supportive of his co-star!

I believe that Rob had no problem with working out and doing what was required of him for his scenes. After all who would go through 3 prior movies and not finish the job. Great job Robert. We are all proud of you. And Kristen your a sweetheart. I refuse to choose between you and Ashley for any reason whatsoever! Alices role is so important to you it feels like it would be an injustice to Bella to do so.
Just little me….
