Supermodel Kate Upton has a bangin' bikini body, thanks to a low-carb diet and rigorous body-sculpting workouts, her trainer, David Kirsch, told Access Hollywood.
Kirsch, who whipped Upton into shape for her two Sports Illustrated swimsuit cover shoots, combines cardio workouts with ab exercises and strength-training to keep the blonde beauty in bombshell shape.
"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 kick-boxing," said David, who trained Kate for her bikini scene in the comedy, "The Other Woman."
Kirsch wanted to make sure the buxom 5-foot-10 Upton maintained her feminine curves while also building lean muscle mass. "Kate already has an amazing, very feminine body, so I just want to tighten everything up to keep her in top shape," said Kirsch, creator of The Ultimate New York Body Plan workout DVD.
"To focus on her abs, we did planks on stability ball, stability ball knee tucks and hanging knee raises, and lots of medicine ball tosses with crunches. For her legs and thighs, we did single leg dead lifts, platypus walks, and reverse crossover lunges. For her arms, we did shadowboxing with light weights."
Kate Followed a Low-Carb, Sugar-Free Diet
Upton also followed a strict low-carb, sugar-free diet that featured lots of salads and vegetables and no processed foods.
"She followed my ABC’s: no Alcohol, Bread, or processed Carbs, and also no sugar," said Kirsch, author of the book, The Ultimate New York Body Plan. "She ate clean, lean protein, lots of salads and greens, and avoided everything processed. She ate small portions five times a day, roughly every three hours."
Kate's bikini scene in "The Other Woman" has been talked about a lot, but she insists she wasn't happy with her body, saying she could have been in better shape. "That was the least healthy I've ever been," she said. "I always try to live a healthy lifestyle, but that was my birthday week."
'I Love My Body Even If Others Think I'm Fat'
Despite making the cover of the Sports Illustrated swimsuit issue two years in a row, the blonde beauty has been widely criticized for being too meaty to be a supermodel. Kate, who has been been called a "lardy, fat pig" and a tacky-looking bimbo, is shocked that her weight is such a hot topic, but has answered the criticism by proclaiming that she embraces her body just as it is.
“It’s kind of funny to think, 'The news is talking about whether I’m fat or not," she told Vogue. “It was hard at first. You sit there and you’re like, ‘Is something wrong with me?’ I can work out and I can stay healthy, but I can’t change some things. I really just live my life. I love my body."
Upton's laid-back attitude about her body is a stark contrast to the harrowing reality of rampant eating disorders among top models, especially those walking the runway during Fashion Week.
The fashion industry has come under fire after reports surfaced that runway models routinely starve themselves, chain-smoke, and abuse laxatives and diet pills to achieve the size-zero physiques that are the holy grail in high fashion.
While the fashion industry has been making an attempt to promote a healthier body image by banning the use of anorexic models, insiders say the aesthetic ideal of the size-zero model will always be in vogue.
