Turnstyle Cycle, Boston

The lights are dim, the music thumps, the experience is fun and inviting during 45-minute beat-based indoor cycling and bootcamp classes. Turnstyle Cycle can brighten your day while helping you boost your cardio and muscular fitness. As music pumps (Turnstyle even lists classes by the artists it'll play) and ambient lights add to the festive atmosphere, you can hop on a stationary bicycle and pedal away at your own speed; an instructor encourages and challenges you in the process. If you want to change things up, Turnstyle also offers a variety of boot-camp classes, incorporating workout equipment such as TRX suspension training. No matter what class you take, Turnstyle will provide you with a towel, and cyclists can borrow complimentary shoes for hopping on the bike.
