So how does Kendall Jenner, one of the most in-demand models of the season and the new face of Calvin Klein Jeans, work out? It s no secret she trains with fitness guruGunnar Peterson, or that she commits to a series of cardio, muscle-building, planking, and ab-sculpting sessions before she hits the runway. But what really energizes her, or anyone for that matter, when it comes to sweating it out? It s all about the music. In Jenner’s case, it’s not pop-infused, teeny-bopping tunes that power her workouts. Think more along the lines of **Drake **s heart-pumping "0 to 100” or the thunking bass of **A$AP Ferg **s "Work." And let s not forget her brother-in-law **Kanye West’**s raps. We re suspecting she receives those fresh out of the studio—not a bad way to get into the gym-going mood.
