Hollywood fitness expert Gunnar Peterson shares his workout playlist

Los Angeles-based celebrity fitness trainer Gunnar Peterson

Kim Kardashian, Jennifer Lopez, Angelina Jolie and Bruce Willis are just a few of the famous faces personal trainer Gunnar Peterson works with every day in his Beverly Hills luxury gym. When it comes to inspiring celebrities to stay in top form, he takes a no-nonsense approach. You have to work out, and you have to work hard.

But what keeps him motivated during his own daily workouts? Peterson shared with Relaxnews his music playlist, emphasizing it is just one of the many he relies on when training. “Obviously I switch around a lot, and I used Pandora on my iPhone a lot too,” he says.

Here is what he's listening to now:  

Nelly, “The Champ”

The Bamboos, “Turn It Up”
Robin Thicke, “Meiple” featuring Jay-Z
