Holy Muscles Batman! Tom Hardy's Been Working Out!

Actor Tom Hardy gained 30lbs of solid muscle for his role as the villain Bane in the new Batman movie, The Dark Knight Rises.

The character of Bane is an escaped prisoner who becomes "abnormally strong after being pumped full of drugs," according to the movie's director, Christopher Nolan.

In February, Tom Hardy said his goal was to weigh 200 pounds before production of the movie started this month. That's 200 pounds in three months! Here he is in the first picture released of him as the villain, Bane, in the Batman movie. He looks huge, (and evil) but unfortunately, we only get a glimpse of his back.

Tom Hardy is no stranger to bulking up for films. He gained around 28 pounds of muscle for his upcoming movie, Warrior.

Some studies report that gaining and losing weight repeatedly, called "yo-yo dieting" can have harmful effects on a person's body. Some studies speculate it can affect your heart while others say it could weaken your immune system. It also seems to mess up your metabolism making it more difficult to lose weight in the future.

Stars gain and lose weight often for roles, as Hollywood tries to make the movies more realistic and true to form. One would assume that the money a star gets for a role makes up for the health risks, but you can't enjoy your money if you're not alive, right? Are stars going too far for roles now?
