'They have a variety of workout regimes from Pilates and yoga to boxing and weight training, kayaking and hiking to training for marathons. They've worked hard to achieve and maintain their amazing bodies,' he added.

Without further ado, we review the top-10 slammin' summer bods!

Brooklyn Decker

This small-town Midwestern girl rocketed to fame in 2007, when she first appeared Sports Illustrated's annual swimsuit edition. By 2010, she'd become the face of the cherished swimsuit edition, gracing its cover.

Earlier this year, readers of Esquire magazine online voted her the 'Sexiest Woman Alive'. Now, she's preparing to make her film debut in the aforementioned Just Go With It.

Sorry, fellas. Decker is happily married to fellow American and top tennis star Andy Roddick.

This perennial favourite of 'World's Hottest' and 'Most Sexy' lists is actual a new mom!

She reportedly does cardio exercise five times a week to keep this sexy figure.

She's famous for playing Alice Cullen in the Twilight movie series, but 23-year-old Ashley Greene is a Florida girl at heart, and is always ready for a day at the beach!

How does actress Jessica Biel stay so fit? Through adventure seeking, of course! Just recently hiked to the top of Mount Kilimanjaro.

Country music singer-songwriter Carrie Underwood, who rose to fame on season four of American Idol, is a vegetarian.

She's also a huge fitness freak, and even keeps a food journal so she can count calories. Obviously, all that hard work is paying off!

Unfortunately, guys, she's engaged to professional ice hockey player Mike Fisher.

This singer-songwriter has a unique sense of fashion and a fab body to go with it.

She's currently getting in shape for her upcoming wedding to comedian Russell Brand, part of which will happen in India, according to Perry's friend Rihanna.

This reality star turned celebutante eats just 1,500 calories a day in order to maintain her amazing figure.

Aniston may have passed the 40-year-old mark last year, but she still has a body to put most 20-somethings to shame.

Oh, and you remember those rumours that Jen had resorted to a baby food diet in order to keep the fat off? Not true.

She just eats smart and healthy, and works her butt of in the gym!

For those who favor the full-figured look, Kim Kardashian in a bikini is sight to behold. But that doesn't mean she eats unhealthy!

According to Women's Health, she's given up all junk food and empty carbs, focussing instead on healthy food like salads with grilled chicken.
