Gunnar Peterson

Trainer to stars like Kim Kardashian and Sofia Vergara, Gunnar Peterson knows that making time for exercise is important. He's responsible for helping Khloe get her revenge body, and boy did she do it. In order to make the most of your time at the gym, make sure to pair strength training with cardio. 

"If you're on a bike or running for 25 minutes, drop down every 5 minutes and do ten squats, ten pushups and ten crunches." 

His pro tip - what you put in your body is crucial too. Allow yourself LOTS of water to hydrate and don't fully restrict yourself, otherwise you'll be miserable. A 'cheat treat' is acceptable, but if you really want results then a full cheat day should be out of the question.
