Hottest Bikini Bodies

The actress attributes her slim-yet-athletic beach bod to a workout of yoga mixed with cardio, and a healthy diet. Keeping active and paddle boarding while vacationing in Hawaii doesn't hurt either.

Biel's athletic body is the total package: rock-hard abs, well-defined arms, toned legs and a tight tush. The actress keeps up her sculpted-yet-feminine build by hitting the track for 40-minute sprint sessions and alternating ten seconds of racing up stairs or around a track with 60 seconds of a slow jog.

The island-native spends plenty of time on the beach, so it's no wonder she looks right at home in a tiger-print bikini that shows off her sexy curves in Barbados.

Alba's entire body is pretty amazing-but how does she get those abs? The actress does crunches while lying on an exercise ball (a Bosu balance trainer, in fact). The result: washboard abs that can keep up with the best bandeau bikini.

Diaz once admitted that she didn't work out until she started Charlie's Angels, but these days her personal trainer, Teddy Bass, calls her one of the most athletic people he's ever met. The actress, who thrives off of physically challenging activities, keeps her mile-long legs taut with sports including surfing and snowboarding.

Beyonce sizzled on the cover of this year's Sports Illustrated swimsuit issue and has been flaunting her beach-ready body ever since. The songbird also heated up the sands in the South of France when she wasn't moving her rock-hard abs and curves on stage.

This year Hudson juggled a career and a young son, but still managed to find time to exercise for about an hour and a half, five to six days a week! The hot mama, who prefers variety in her work out routines, remained well toned by engaging in outdoor exercises including long runs, canoeing, hikes and scuba dives.

Cruz is highly noted for her breathtaking red-carpet looks and underneath it all she is equally stunning. The actress looked svelte while vacationing in destinations such as Ibiza and St. Barts this year.

Gisele may have hung up her wings at Victoria's Secret this year, but the Brazilian beauty has proved that she is still what Alexander McQueen once called "The Body." Her flawless physique and mile-long legs not only make a wearing a string bikini look easy but landed her the richest supermodel in the world title in the Guinness Book of World Records.

Bosworth's shrinking frame raised eyebrows last year, but this year she looked better than ever. The Blue Crush actress hit the beach and showed off her sporty side while snorkeling.
