Who knew Katie Holmes was a speed demon? Well, with her love of spinning classes no matter what city she's in, the actress is showing her need for speed. From Soul Cycle in New York City to REV in Beverly Hills, Holmes takes to the stationary bike as often as she can to burn at least 350 calories per 60-minute session. Even during the holidays, Katie was spotted leaving spinning classes a few times a week to regulate those holiday pounds, and sometimes she takes daughter Suri along for the ride. Try out a spinning class at your local gym for an intense cardio session like Katie's.
