Which of the following best describes the "Red" heart rate zone?

The "Red" heart rate zone is characterized by high effort levels, where the body is working at or near its maximum capacity. In this zone, it is common to experience a significant calorie burn due to the increased demand for energy. Training in the Red zone typically occurs when participants are pushing themselves through intense workouts, which involves elevated heart rates that can lead to improved cardiovascular fitness and endurance over time.

This zone is crucial for challenging the body and driving adaptations that result from high-intensity training. The focus in the Red zone is on maximizing effort and performance, making it an essential component of the Orangetheory Fitness training philosophy, which emphasizes varied intensity to enhance overall fitness outcomes.
