At Orangetheory Fitness in Naperville, Illinois, our tough high-intensity interval training (HIIT) sessions will continue to energize your body and mind long after your workout has finished.

Orangetheory Fitness one-hour group sessions are a perfect blending of cardiovascular and strength training. Using well-maintained, state-of-the-art equipment, your friendly personal gym trainer will lead you through challenging intervals of treadmill training, indoor rowing, TRX suspension training, weight training blocks, and floor exercises.

Orange 60 sessions are heart rate-monitored and have been designed to keep your heart rate within a target zone in order to stimulate metabolism and increase energy. What results is the Orange Effect—more energy, visible toning, and extra calorie burn for up to a day and a half after your session.

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.
