The different heart rate zones illustrate the training intensity you reach during your workout. The Polar system has 5 different zones, which are also displayed with 5 different colors: gray, blue, green, yellow and red. Each zone has its purpose and shows the intensity. The gray zone is optimal for recovery, the blue zone improves basic endurance and fat burning, the green zone improves overall aerobic fitness, the yellow zone increases maximum performance for shorter sessions, the red zone helps fit athletes develop speed.
