Celebrities Who Train With Harley Pasternak

If Tracy Anderson has half of Hollywood on her client roster, Harley Pasternak has the rest. What started out as a side job has turned into a full-blown career — three studios and 12 trainers later, it's a rare day if Harley isn't jetting somewhere in the world to train a client. Lady Gaga, Kanye West, Robert Pattinson, Megan Fox, and Katy Perry are just a small dent of the A-list celebs who Harley works with, and for over 10 years, he's been developing his 5 Factor philosophy of diet and exercise: five 25-minute cardio circuits per week coupled with eating five times a day (three meals, two snacks).

Keeping with Harley's 5 Factor ways, let's take a look at five of the hottest female celebs he's currently training.
