These just in!

Taken a few hours ago - Taylor Lautner on set working out, pumping up those muscles before the cameras started rolling.

I'm on my blackberry right now so I can't see every photo clearly but those look like bicep curls, triceps, standing rows, flies too. Those bands - those are super bands. Hayley makes me do core rotations with those bands combined with an oblique dip on a bench. Killer.

Anyway, by all accounts Taylor has been working out vigorously to become wolf-worthy as he'll be featured topless in several scenes.

There's video of him training too. Enjoy!
