Best Revenge Body: Katie Holmes
This Broadway star and overall badass mama keeps her shape in check with frequent Soul Cycle classes -- a FITNESS editor favorite! She was even spotted at a class on her 32nd birthday. Now that's dedication.
Runner-up: Katy Perry
Best Legs: Blake Lively
Good genes, yes. But those long and lean stems are the result of hard work, too! The bombshell perfects squat jumps and lunges to keep her gams looking great. Now if only we could forgive her for taking Ryan Reynolds off the market....
Runner-up: Heidi Klum
Best Arms: Michelle Obama
In what many considered to be a risky move, the First Lady donned a sleeveless dress at the Democratic National Convention this year, sparking quite a buzz. But really, with biceps like those can you blame her? Here's to four more years of striving to get MObama-worthy guns!
Runner-up: Ashley Greene
Best Cleavage: Kate Hudson
Aside from looking smokin' hot on Glee, the mom of two has been pictured toting her newborn son Bingham around...which clearly needs to be the newest fitness trend if it scores an upper body like hers.
Runner-up: Amy Poehler (for that jaw-dropping Emmy dress)
Isaac Brekken/Getty ImagesBest Abs: Gwen Stefani
Though her band No Doubt has had quite the comeback year, Gwen's abs have been holding down the fort since the group's start in 1987. (Or in song speak: Hey Baby, your abs Underneath It All are Hella Good.)
Runner-up: Stacy Keibler

Best Butt: Eva Longoria
Just one of her best assets (pun intended), Eva's proud of her rump! Crediting her backside to early morning workouts and a sugar-free diet, she's just one of the stars who recently bared her buns for the coffee table book Asleep at the Chateau. Go ahead and Google it, we'll wait.
Runner-up: Jennifer Lopez
Best Curves: Jennifer Lawrence
The Hunger Games and Silver Linings Playbook actress stole our hearts when she recently told the press she would never "starve herself" just to get a part. She prefers to look strong and healthy over "thin and underfed."
Runner-up: Sofia Vergara
Best Back: Julianne Hough
What's the secret to Seacrest's girlfriend's sexy back? Dancing -- and lots of it!
Runner-up: Charlize Theron

Best Bride-to-Be: Jennifer Aniston
Jen's been topping our list for years and we have no doubt that she'll make one heck of buff bride. Because really, just lugging that engagement ring around has to be a workout in itself!
Runner-up: Britney Spears
Best Body After Baby: Beyoncé Knowles
She bounced back fast, losing the baby weight with the help of breastfeeding, a protein-packed diet, and tons of treadmill time.
Runner-up: Reese Witherspoon
Fab After Forty: Halle Berry
Halle is like a good wine, she just keeps getting better and better with age. The secret to her success? Strength training, cardio, and a super-clean diet. Sorry, no easy passes here!

Kevin Mazur/Wire ImageBest Celebrity Slimdown: Pink
The rocker mom gained 55 pounds during pregnancy, courtesy of some cheesecake (and lots of it!). With the help of celebrity trainers like Jillian Michaels and Jeanette Jenkins, she whipped herself back into shape, and is once again the proud owner of a set of sexy, flat abs.

This U.S. soccer star wins the gold for her solid core (she's been known to plank for four minutes!), super-strong legs, and bring-it-on biceps.
Silver: Allyson Felix

All we can say is thank goodness Ryan Lochte does a sport that doesn't require a top. Think about it. Imagine how much we would've been missing out on if he had taken up fencing instead?
