I came across the concept of heart rate zones while watching
one of Andrew
Hubermanβs interviews. That was a fascinating piece of information.
The zones are based on oneβs maximum heart rate which is a function of
age and can be simply calculated as follows:
max heart rate = 220 - age.
After that Iβve found a website that talks about how exercising in different zones burns different types of fuels, i.e.Β fat, carbs or protein. It turns out elevating heart rate during an exercise does not necessarily help with weight loss. If you want to burn fat primarily then stay in Zone 1 or 2.
Zone 3 hits all of the three source of fuel. Thus my target is Zone 3.
| Zone | Also known as | Intensity level | % of max heart rate | Fuel source |
|---|---|---|---|---|
| Zone 1 | Warm-up, recovery, easy. | Moderate-low. | 50% to 60% | Fat. |
| Zone 2 | Aerobic, endurance, base, light. | Moderate. | 60% to 70% | Fat. |
| Zone 3 | Tempo, threshold, cardio, moderate. | Moderate-high. | 70% to 80% | Fat, carbs and protein. |
| Zone 4 | Lactate threshold, redline, hard. | High. | 80% to 90% | Carbs and protein. |
| Zone 5 | Anaerobic, V02 max, peak, maximum. | Very high. | 90% to 100% | Carbs and protein. |
