Kate Upton's Crazypants SI Cover Body Workout
kate-upton-david-kirsch Unless you’ve fallen off the social media map this week, you couldn't help but see an image of Kate Upton’s barely-clothed body in the much-anticipated annual Sports Illustrated swimsuit issue every time you press Refresh. The bare-it-all beauty looked to David Kirsch, a fitness and wellness expert, founder of the Madison Square Club in NYC, and the man that, well, just about every have-to- look-good-practically-naked model has on speed dial.

Upton may have hit the genetic jackpot, but she still works to stay in top shape. “As far as nutrition," says Kirsch, "I had the benefit of being able to cook for her when we started training in the summer and getting her into my mindset and philosophy of sound mind, sound body — eating clean protein, lots of salads and greens, and avoiding everything processed.” (Kirsch says she even smuggled in a bag of sliced cucumbers and celery to snack on at Knicks game. Now, that is dedication.) When she was really down to the wire, Upton looked to Kirsch’s Protein Powder, AM Daily Detox, and Kirschbar The Perfect Snack to stay energized.

Then there were the workouts. “The idea was to step up the intensity and duration of the workouts, making it a strict cardio and sculpting boot camp that entailed body weights and resistance bands, sprinting and calisthenics, shadow and kickboxing,” says Kirsch. “Kate is blessed with the most gorgeous feminine curves and I was determined, no matter how hard we trained, that I wasn’t going to let her lose a crazy amount of weight,” says Kirsch. “The goal was to lengthen and tone her thighs and inner thighs, and keep her butt perky — it wasn’t about dramatically changing her body."

Translation: Sweat sessions seven days a week. Initially, Kate worked out twice a day, then wound down to one hour a day, five or six days a week. “Pushing past her perceived limits is what really got her body into the shape it was in for the cover,” says Kirsch.
