Studeo 55 in Vancouver BC just trained 6 of the top actors in the upcoming Tron Legacy, and 16 actors in the 3rd sequel of the Twilight series. Nikki Reed, Bryce Howard, Pattinson, Reaser, Greene, etc... Here's what Nathan Mellalieu, gym Owner and celebrity trainer says about their training:

Since this Twilight will be the most action-packed of the three movies, (and will have the most epic battle scene ever), the actors had to be trained for scenes where they could literally fight each other. The fighting scenes are all performed by the actors themselves. Every person trained was involved in battles in the movie.

The actors were either werewolves or vampires. Vampires are athletic, crazy strong and explosive, but they are still beautiful supermodels, therefore couldn't take on the physique of a hardcore athlete or body builder. Their training was very intentional - every move had a specific purpose in conditioning their bodies for this movie.

A lot of crossfit style moves were used at high intensity intervals with multiple reps and minimal rest. Very different from an bodybuilder or NFL workout where they lift as heavy as they can then rest for 5 minutes, or an athlete that would run for 45 minutes straight.

The movements were dynamic and complex, involving many muscle groups.

"Unlike the wimpy core workouts where people kneel on a yoga ball and throw a tennis ball against the wall, these had to be moves that are actually used in battle," Nathan says. "Honestly, a lot of the 'core' workouts that are popular today are nothing more than mild circus acts."

Full impact MMA-style fighting sequences were practiced in Studeo 55's new padded fighting room (yes, Nathan got to spar with some of the hottest up and coming celebs.)

The actors ended up being more fit and more beautiful than they'd ever been. Here's 2 actual testimonies from this week:

“You guys were the best at this job! We will miss you terribly... Thanks for changing our lives (not to mention our a**es)" - Nikki Reed

“We have trained at gyms all over the world, but nothing compares to Studeo55!” - Elizabeth Reaser
