WHAT ARE HEART RATE ZONES?
We all have a personal resting heart rate ‘a minimum heart rate’ and a maximum heart rate. And between these values are different HR zones that correspond to training intensity and training benefit.

FIVE HEART RATE ZONES
There are five different heart rate zones (1–5) and your training plan can (and should) include workouts in all five zones. This HR zones chart shows the level of intensity and percentage of Maximum Heart Rate used in each one.

HEART RATE ZONE 1: 50–60% OF HRMAX
This is the very low intensity zone. Training at this intensity will boost your recovery and get you ready to train in the higher heart rate zones.

HEART RATE ZONE 2: 60–70% OF HRMAX
Exercising in heart rate zone 2 feels light and you should be able to go on for a long time at this intensity.

HEART RATE ZONE 3: 70–80% OF HRMAX
Working out in heart rate zone 3 is especially effective for improving the efficiency of blood circulation in the heart and skeletal muscles

HEART RATE ZONE 4: 80–90% OF HRMAX
Heart rate zone 4 is where the going gets tough. You’ll be breathing hard and working aerobically.

HEART RATE ZONE 5: 90–100% OF HRMAX
Heart rate zone 5 is your maximal effort. Your heart and your blood and respiratory system will be working at their maximal capacity.
