Any good gym blurs the line between exercise and fun. But at BK Cycle, one might confuse working out with going to a club. Energetic music plays during all classes, which take place from early morning to late evening. As the beats echo throughout the room, enthusiastic teachers pump up students to pedal faster and harder on their stationary bikes. The exuberant exercise gives an intense cardiovascular workout and helps burn calories more effectively than throwing a Big Mac into a bonfire.
