"I'm a Beverly Hills-based strength coach, personal trainer, however you want to look at it," he said while introducing himself to Men's Health when we dropped by his Hollywood facility. "Because of where I am, you meet a lot of people in the entertainment industry as well as athletes from a number of different of different sports."

But Peterson's location isn't the only reason he's successful. The veteran trainer is clearly an expert at coaching people to success, as is abundantly clear from his wide-ranging A-list clientele. Peterson has worked with actors like Hugh Jackman, Matthew McConaughey, and Sylvester Stallone, reality TV royalty from the Kardashian/Jenner family, and pro sports teams, most recently as the L.A. Lakers Director of Strength and Endurance Training . He's also one of the expert trainers included in Chris Hemsworth's new Centr app .

No matter who he trains, or for what purpose, Peterson's philosophy is the reason for his success. That's why he's so popular-it's not some secret formula or Hollywood showmanship. Just smart programming and hard work.

"The goal is to get [my clients] where they want to go, from a performance standpoint and of course from an aesthetics standpoint" he said. "We do a lot of strength training, and of course we work on flexibility, cardiovascular strength as well."

Peterson opened up his gym and walked us through some of the moves he uses in the workouts he creates for his A-list clients. You can plug the exercises into your current plan depending on what you're already doing, or use the routine as a standalone workout since it checks just about every box. "We hit multiple planes of motion, upper body, lower body, push, pull, and of course the all-important core."

Some of these moves require specialized gear you might only find in a Hollywood gym-never fear. We'll provide an easy substitution for each one that you should be able to pull off just about anywhere.
