Heart Rate Color Zones

Many athletes use heart rate zones to measure and increase
their cardiovascular strength and improve their level of fitness. A
heart rate zone is a set range of heartbeats per minute. There
are five commonly accepted heart rate zones in order of
intensity. Generally, heart rate zones are calculated based on
percentages of your maximum heart rate.
Gray Warm Up Relaxed and easy pace
Blue Easy Comfortable pace; conversational
Green Aerobic Moderate pace; optimal cardiovascular training
Orange Threshold Fast pace; forceful breathing
Red Maximum Sprinting pace; unsustainable for a long period
of time
Fitness Goals
Knowing your heart rate zones can help you measure and
improve your fitness by understanding and applying these
principles.
• Your heart rate is a good measure of exercise intensity.
• Training in certain heart rate zones can help you improve
cardiovascular capacity and strength.
• Knowing your heart rate zones can prevent you from
overtraining and can decrease your risk of injury.
If you know your maximum heart rate, you can use the table
(Heart Rate Zone Calculations) to determine the best heart rate
zone for your fitness objectives.
If you do not know your maximum heart rate, use one of the
calculators available on the Internet. Some gyms and health
centers can provide a test that measures maximum heart rate.
The default maximum heart rate is 220 minus your age.
