Sweating With the Stars: Sundance Edition

While the rest of us have been enjoying this lovely Los Angeles weather (when we're not working), the celebs private-jetted their way to Park City, Utah this week for the Sundance Film Festival.

And although most of their time was spent gifting, schmoozing, and boozing, many health conscious Hollywoodlanders took a little time out to hit the slopes.

A moderate Snowboarding or Skiing sesh burns about 350 to 550 calories per hour (depending on your weight). And a vigorous round can torch 450 to 725 cals. Factor the fact that you're having a blast while doing it, and it's like a workout freebie.

Hottie brothers Chris and Liam Hemsworth (Miley Cyrus' ex) took the trip as an opportunity to learn how to grind at Oakley's "Learn to Ride" event fueled by Muscle Milk.

Though he's usually found fueling up on pimp juice, Lil' John took his turn on a board after chugging Muscle Milk Light's new Cafe Latte flavor protein shake. These things are the bomb b-t-w. Only 160 cals, 0 g. sugar, 5 g. fiber, and 20 g. protein.

As you can see, Jon can board with the best of them.


Jermaine Dupri...

...Anne Heche...

...and Carmen Electra also joined in the fun. Although it appears Electra felt more comfortable playing the snow bunny role.
