The Beverly Hills fitness trainer has worked with the likes of Pete Sampras, the Los Angeles Lakers, the Kardashians, Hugh Jackman and many more.

A new year means New Year's resolutions and there's arguably no one more in demand this time of the year than a fitness trainer (at least in normal times). This week brings in strength coach Gunnar Peterson to talk all things fitness, health and nutrition, with a touch of celebrity status mixed in.

Though he loathes being dubbed a "celebrity trainer", he has worked with plenty of big names including Pete Sampras, Matthew McConaughey, Sylvester Stallone, Dwayne Johnson, Hugh Jackman and the Kardashians (he's even appeared on "Revenge Body with Khloe Kardashian").

"Because you work with some celebrities, you're only a celebrity trainer, but how about the fact that I work with doctors, lawyers, athletes, stay-at-home moms," Peterson says. "I work with people across the board. You name a vocation, I've probably worked with them. I've been doing this for 30 years."

Peterson is also currently the head of strength training for the Lakers, who just won the 2020 NBA Finals. He'll surprise you with his take on who actually works out the hardest as he shares tales from his Beverly Hills gym and talks about the power of motivation and the importance of supplements.

Best of all, he explains what was so great about working with Sampras, who had a special request each time he worked out at Peterson's gym: turn the air conditioning off. 

"He had a thing where he liked to train in the heat," Peterson says. "We used to call it 'Pete Heat' and the gym was roasty toasty... His athletic learning curve second to none. Phenomenal athlete, phenomenal person, fun, funny, smart. I loved the hours that he was in there."
