17. Khloe Kardashian

Khloe’s personal trainer is none other than Gunnar Peterson who has also been the celebrity trainer for Halle Berry, Jennifer Lopez, Sofia Vergara and Penelope Cruz. Her work outs with Gunnar consist of weight training using medicine balls and boxing circuits. Khloe has exclaimed, “I love to box. Boxing is really fun, and it’s such a stress reliever.

I’m just so busy having fun, I forget that I’m working out; 45 minutes go by and I’m dripping wet. We do a lot of workouts together, my sisters and I, and we go on a lot of hikes and walks outside. I never like doing the same workout two days in a row, I just get bored. I’ll try anything except surfing. I won’t go in the water. I’m terrified of whales and sharks. I’ll go in a pool, though”
