Kate Upton literally burst onto the Sports Illustrated scene when she posed for cover of the iconic swimsuit issue in 2012. The buxom blonde hired powerhouse trainer Justin Gelband months before the SI shoot to get her bodacious bod in tip-top shape. The dynamic duo worked out five days a week with a mix of circuit training exercises that changed daily.
"Since the first day I met her, she wanted to come in and change the industry by saying curves are sexy," Gelband has said. "She's such a great role model for all the young girls out there."
