While it may have been Taylor Lautner's killer abs that stole the show at the box office hit movie Twilight Saga: New Moon that opened this weekend, there are still those more partial to Robert Pattinson's physic. Not generating quite as much buzz for his subsequent bulking up and toning up as his Lautner teen wolf counterpart, Pattinson did adhere to his own workout and fitness routine in reprising his role as one of the most famous vampires to date.

As it turned out, Pattinson was in fact instructed by his movie producers to head to the gym as a means to curb his habits of late night drinking and his penchant for cheeseburgers. while Robert obviously wasn't lifting nearly as much as Taylor, he did take up running and karate to keep himself fit and in top form. As he does go shirtless in the Twilight New Moon movie, there no doubt was a bit of an added incentive.

So how did he build up his biceps and chest in order to dare to bear? Exercises like dumbbell press, bench press, and inclined dumbbell press would do the trick for the pecs. By pairing higher weights with less reps, you will be able to gain more muscle mass and subsequently bulk up. This would look like doing a set of 12 reps with a weight that you can maintain for that amount, then go up in weight and cut back to 8 reps for the second set. Follow this with yet another increase in weight and cut the reps down to 4. Rest completely between each set, as each set should be an all out maximum effort.

For biceps like Mr. Pattinson, you will do the same sort of idea but with bicep curls and preacher curls. Start with 12 reps, then go up in weight for 8 reps, and end with the highest weight for 4 reps. And whenever you work one muscle group you should aim to work their counter parts, so for the biceps that would be the triceps, so you should do triceps extensions and bench dips. To add weight for the bench dips, you will plant your arms on the backside of one bench and then elevate your legs on another so that you are above the ground and then rest a weight in your lap for the duration of your sets.

Surely if you want to look like the hunky vampire Robert Pattinson portrays in Twilight New Moon, you've got to work for it! Finish your workout in the gym with a run to get in some calorie blasting cardio. The jury may still be out as to who actually looks best shirtless, Robert Pattinson or Taylor Lautner, but either way you can steal their workout and fitness moves!
