Using top-of-the-line, well-maintained gym equipment, our personal trainers will lead you through an energy-filled 60-minute group session that focuses on three main areas: treadmill interval training, indoor rowing machines, and weight room or resistance training blocks.

Orangetheory workouts are backed by the science of excess post-exercise oxygen consumption (EPOC) and have been constructed to keep your heart rate within a targeted range in which your metabolism is stimulated and your energy will be increased. This will result in the Orange Effect: Extra energy and calorie burn for up to a day and a half after your workout!

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.
