Many runners, bikers, and other athletes are using heart 

rate “zones” to measure and increase their cardiovascular 

strength and improve their level of fitness.

A heart rate zone is simply a range of heartbeats per 

minute (bpm). The five commonly accepted heart rate 

zones are numbered from 1–5 according to increasing 

intensity. Generally, heart rate zones are calculated based 

on percentages of your maximum heart rate. See Table 1 

to learn some of the effects of exercise as your heart rate 

reaches each of these zones during a workout.

Knowing your heart rate zones can help you measure 

and improve your fitness by knowing and applying these 

principles:

•  Your heart rate is a good measure of workout 

intensity.

•  Training in certain heart rate zones can help you 

improve cardiovascular capacity and strength.

•  Knowing your heart rate zone can prevent you from 

overtraining and decrease your risk of injury.

See Table 1 to learn the benefits of training in each heart 

rate zone.

If you know your maximum heart rate, you can enter it 

and allow the Forerunner to calculate your heart rate zones 

based on the percentages shown in Table 1 (see “Setting HR 

Zones Manually” in the Customizing section). However, 

the Forerunner 301 has a built-in feature called AutoLearn, 

which determines your heart rate zones automatically and 

continues to adjust them as your fitness level improves. To 

determine your heart rate zones, the Forerunner pinpoints 

your lactate threshold—the point where your body switches 

from aerobic energy consumption to anaerobic energy
