tell you right now.. I know several celebs and their training regimines... First step, they ALL have the bombest trainers, which in LA, is purely word of mouth. Now remember, even most bad trainers can get a routine going, but these trainers are good because they are unbelievable motivators and teachers. They get their clients excited about the regimines and since stars' number one priority is their appearance, it's not difficult to justify working hard. Anyone who applies themselves could get from natural unfit physique to usher inside of a year. Don't forget guys, he was a professional dancer well before he went in a solo career.
