The rest of Kim Kardashian's workout will consist of dead lifts, power squats, cardio boxing and bouts on the rowing machine. The combination will target all parts of her body, ranging from arms and shoulders to butt, thighs and core.

Some of Peterson's clients include Halle Berry and Sofia Vergara. The fitness guru admits that the use of the sled is so punishing Vergara curses at him in Spanish while she is pushing the apparatus along.
