Barry's Bootcamp
In its 10 years, Barry's has become one of the most popular fitness training centers in Hollywood. With a client roster that includes Jake Gyllenhaal, Katie Holmes and Biggest Loser host Alison Sweeney, the gym seeks to "be the best boot camp in the world." And it seems to be working—for those willing to endure some pain for their gain, Barry can beef up or slim down any bod.
