Zone 2 is considered the target range for aerobic and base fitness work and should be about 60-70% of your HRmax. Zone 3 is the range for aerobic endurance work and should put you at about 70-80% of your HRmax.
What zone should you be working at to improve your fitness levels?
Zone 2 (60-70% max hr) is great for building general endurance and burning fat, as well as helping to improve your cardio fitness and blood flow to the muscles. Zone 3 (70-80% max hr) is a great level for anyone wanting to burn fat and improve their aerobic capacity.
What zone do you want to work out in?
For optimal cardiovascular health, the American Heart Association recommends at least 150 minutes per week of moderate-intensity aerobic activity (zones 1 to 3). Or if you want to get more benefit in less time, aim for 75 minutes per week of vigorous aerobic activity (zones 3 to 4).
What zone builds muscle?
Zone 3 – aerobic exercise: Exercising for 10–40 minutes with a heartbeat of 70-80% of your maximum heart rate will not only burn fat effectively, but will also strengthen muscles as well as building their endurance capabilities.
Does Zone 2 or Zone 3 burn more fat?
The body burns fat as fuel for exercise at lower intensities (in heart rate zones 1 and 2), whereas it burns carbohydrates as fuel at higher intensities (zones 4 and 5).
Is it OK to exercise in Zone 4?
Although exercising within heart rate zones 1 and 2 does not burn much fat or cause the body to feel that fatigued, you will still feel refreshed, content and find it easier to sleep after sessions in this zone. For those wishing to increase fitness or lose weight, exercising in heart rate zones 3 and 4 is sufficient.
