“ HEART RATE ZONE 2: 60–70% OF HRMAX
Heart rate zone 2, light
Exercising in heart rate zone 2 feels light and you should be able to go on for a long time at this intensity.
This is the zone that improves your general endurance: your body will get better at oxidizing – burning – fat and your muscular fitness will increase along with your capillary density.
”
主要是心率,心率达到zone 2。不能只看时间。 |
