High-energy beats from artists such as Flo Rida, B.o.B., and the Black Eyed Peas bounce forth from the spinning studio at Rock Creek Sports Club, where nationally certified trainers lead stationary cyclists through challenging routes. In addition to these pop-powered workouts, the studio hosts more than 50 other fitness classes, an array of options that prompted the editors of Bethesda Magazine to name the studio 2012’s Best Neighborhood Gym. Zumba classes encourage students to boogie away calories to latin beats, and boxing clinics incorporate one-on-one attention from Golden Glove winner Russell Davis. The team of trainers can also coach visitors through the weight-loss process, or helm small group workout sessions capped at eight participants. The gym also welcomes independent workouts, with equipment such as treadmills, benches, and weights awaiting a few breathless reps of their own.
