Download the Zenergy app today to plan and book your classes! From the Zenergy iPhone app you can view class schedules, book and manage your existing reservations, buy classes, view ongoing promotions, as well as view studio information. The Zenergy workout is specifically designed to strengthen the body, the heart, and the mind while burning maximum calories. Light handweights are used to engage the upper body while movement in and out of the saddle works your core and lower body. Cleated shoes are worn to increase riders connection between the foot and the bike, engaging the hamstrings and glute muscles, resulting in lean, toned legs. The philosophy is simple; to help you forget about how hard you are working, instead allowing you to clip into the bike and out of the rest of the world.
