Gyms in L.A. are always coming up with one new class or another — cardio boot camp, supercharged spinning, power yoga — so it was only a matter of time before the dodge-ball craze found its way to Crunch on Sunset Boulevard, which has been hosting exciting dodge-ball games (or classes) for the past year. Started last summer as a seasonal offering, dodge ball, which is "taught" by instructor and actor-dancer Dollar Tan, has become a year-round class that attracts men and women who like to compete and get a great workout in the process. A regular crowd often shows up to throw, dodge and catch the red rubber balls, but new players are always welcome.
