How does 'Scrubs' star Sarah Chalke maintain her svelte physique? She practices a high-intensity workout called Xflowsion, which combines martial arts, yoga, and power dance.  "There's so much variety that an hour and 15 minutes just flies by and you never get bored," the comedic cutie tells Fitness magazine.

"It incorporates a lot of yoga, which improves your flexibility and your strength, and then you get to do boxing. That's my favorite part, because it's such a great release. I feel so much stronger now, and I definitely have lots of energy," she said.

When questioned about the crazy Hollywood lifestyle, Chalke takes the honest route:

"There are definitely pressures in this business to look a certain way. I believe you have to try to find a happy medium and put your health first. I don't even own a scale, actually," says Chalke.

That's some REAL and REFRESHING Tinseltown inspiration!
