Myzone Heart Rate Zones – Purposes and Benefits
Do you feel like you’re not working out hard enough unless you’re in the red zone? Some people do seem to think they’ll not get any benefit from their workout unless they’re really crushing it, barely able to talk and sweating profusely but each of the heart rate zones has their purpose and ideally you should end up with an app calendar that shows a range of different levels of intensity.
The Grey and Blue Zones
Gray: 50-59% MHR (1 MEP per minute) and Blue: 60-69% MHR (2 MEPs per minute)
Purpose: These are moderate intensity zones and should be used for warm up/recovery, long duration exercise and to build an aerobic base for beginners to exercise.
Benefit: Working out in the grey and blue zones helps build new capillaries in the muscle to improve blood flow and the supply of oxygen and nutrients to working muscles. There would also be an increase in mitochondria (the muscles powerhouse) and an improved ability to use fat as a fuel source.
The Green Zone
Green: 70-79% MHR (3 MEPs per minute)
Purpose: Moderate (70-74%) to high (75-79%) intensity zone for steady state aerobic training or recovery zone for tempo/pace training and high intensity interval training
Benefits: Helps to build an aerobic base and enable the body to work closer to aerobic capacity (maximal ability to efficiently take in and process oxygen). Improves recovery efficiency.
Yellow: 80-89% MHR (4 MEPs per minute)
Purpose: This is a high intensity zone used for threshold training (maximal steady state training), the work phase of tempo/pace training and the work phase of high intensity interval training
Benefits: The yellow zone expands aerobic capacity and builds lactate threshold meaning you can workout harder and for longer, increasing endurance and stamina and improving speed and power. Recovery improves. Also, you crush those calories!
Red: 90-100% MHR (4 MEPs per minute)
Purpose: This is a high intensity zone for the work phase of high intensity interval training
Benefits: Same as yellow zone
