Riding a stationary bike is much easier than riding a bike made of stationery, which wobbles under the weight of written emotions and wind-resistant letterheads. Pedal away on the real thing with today's Groupon: for $30, you get five 50-minute classes at Pedal Spin Studio (a $65 value), valid at the locations in Claremont and Rancho Cucamonga.

Pedal Spin Studio's blend of energetic music, inspiring visualization techniques, and motivational instructors make gaining health and shedding stress a breeze. Choose from classes such as Intro to Spin, an ideal fit for first-timers that teaches spinning fundamentals, edifies about stationary set-up, and enlightens minds with knowledge of the hallowed five core movements. PedalSPIN, the facility's namesake class, dominates the calendar with low-impact workouts as many as four times per day, and the PedalParty class transforms the cheery studio into a frenetic nightclub of fitness. Other classes include PedalYOGA, Rock & Soul RIDE, and Earlybird SPIN, which begins at 5:30 a.m. Exercisers may anticipate burning 400 to 1,000 calories per workout on the fixed-gear bikes or a minimum of 200 calories chasing down loose-gear bikes roaming the studio. Consult the schedule and FAQ page for more details.

Exposed brick walls and hardwood floors provide a minimalistic workout setting, mentally reinforcing how little separates determined riders from their fitness goals. First-time spinners should inform their instructor of their newness to ensure proper cycle adjustment and to receive assurances that, despite furious pedaling, the bike will not levitate out of the building and float cinematically past the moon.
