Good things come to those who sweat, and the Orangetheory workout delivers results that are backed by scientific research. You'll keep up your heart rate and boost your metabolism in a workout that moves through rowing machines, treadmills, ellipticals and weight stations, all in just one action-packed hour. If you're in the mood to compete with yourself, take a look at the board at the front of the room, which shows how much you're burning.

Every Orangetheory class is led by a trainer who's there to give personal attention to every participant. The gym trainer will explain your exercises and also show alternatives. The combination of a group setting and the results that come from working one-on-one with a trainer will leave you feeling energized and motivated to test your limits. No two workouts are the same, so your experience will be fresh every time.

Everyone, regardless of body shape or fitness level, is welcomed at Orangetheory. Our coaches work hard to make a personal connection with everyone in the class. Our friendly and helpful trainers are thrilled to answer your questions and help you reach your best self.

Backed by the science of post-exercise oxygen consumption (EPOC), our heart-rate monitored training is designed to keep heart rates in a target zone that stimulates metabolism and increases energy. Our clients burn an estimated 500 to 1000 calories per workout. We are 5 zone heart-rate interval training.







Working out in a group provides accountability and structure to help achieve fitness goals. You are more likely to get a great workout and better results from the well-rounded movements and pace direction you get in a group setting. The session motivates each other to pick up the pace and reach beyond plateaus. People who workout in groups stick to their goals more consistently than those that workout alone.
