The physiological theory behind Orangetheory is known as excess post-exercise oxygen consumption (EPOC). During the course of a session, you will perform focused 10-30 minute intervals that use your entire body and stimulate your metabolism. After each exercise, you will feel increased energy. After the session, your body will continue to burn more calories as it tries to recover from the strong bursts of activity. Challenge your expectations and your limits with 60 minutes of interval training. Intense bursts of activity, combined with fatigue-level strength training give you an amazing workout that is always challenging and fun. An Orangetheory workout will give you the energy you need to feel great, look great, and achieve your fitness goals.
