With loud, foot-thumping music and colourful lights dancing off the walls, it felt like we had sauntered into a discotheque, when we stepped into the spinning studio, Revolution. Started by fitness enthusiast (and a lawyer by profession) Annie Khan, the three-month old studio packs in 20 high-tech Spinner Blade Pro bikes in its indoor cycling facility, the only studio in India to house these imported stationary bikes. It also offers a separate space where Zumba, kickboxing and yoga classes are conducted. The spinning classes are conducted twice a day — morning and evening — by various in-house instructors and we signed up for a morning session.
