About Heart Rate 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. The five

commonly accepted heart rate zones are numbered from 1 to 5

according to increasing intensity. Generally, heart rate zones are

calculated based on percentages of your maximum heart rate.
