Taylor Lautner is loving his new fitness so much, that he’s planning to open a gym.

The Twilight star went from actor to hunk by bulking up for the film’s sequel Twilight Saga: New Moon and has now trained to become a personal trainer.

It’s though Taylor is using his gym knowledge as a fall-back, in case he can’t get any more movie work in the future, once the vampire series comes to an end.

“His self-esteem shot through the roof when he bulked up for The Twilight Saga: New Moon and he wants other people to experience that feeling,” a source said.

“He wants to open up his own workout center one day,” the insider added about beefcake Taylor.

Good news however, because Lautner does have at least one more film coming up – in 2010 he’ll co-star alongside rumored on-off girlfriend Taylor Swift in romantic-comedy Valentine’s Day.
