Orangetheory Fitness is a 5 zone heart-rate-based interval training class comprised of both cardio and strength training. During a workout, members focus on Zones 3(challenging but doable), 4 (uncomfortable), and 5 (all out/sprint effort). These are individually calculated for each Orange theory Fitness member before class. The workouts are designed to produce 12 minutes or more in Zones 4 and 5 combined during the workout. The goal of this is to achieve EPOC. (Excess Post-Exercise Oxygen Consumption). Each minute spent in the Orange or Red Zone is considered 1 Splat Point!
