Kate Upton inspires girls to push harder for fitness

Supermodel Kate Upton "inspires girls" to push themselves harder in the gym, says her personal trainer Ben Bruno. The 24-year-old has been announced as the cover girl for Sports Illustrated magazine's annual Swimsuit edition this year for the third time in her career.

According to Bruno, Upton's dedication to training serves as an inspiration to other women. "I've personally seen Kate already inspire a lot of girls to (lift) heavier because in their mind they think that they're going to get big and bulky, but then they see Kate doing it and think, 'Well, I guess I don't have to worry about that'," Bruno told eonline.com.

Bruno said that Upton was very disciplined when it came to getting in shape for the nude shoot. "A lot of times in the afternoons, we would either go together or she would go with her dog, Harley, hiking just to get outside. Or, for a while when we were really amping up for the shoot, we would do an hour of tennis every day," he said.
