Is Fat Burning Zone a Myth?
However, a closer look at the studies revealed that while a higher percentage of fat is used for low intensity exercise, there are more total calories and more total fat calories used for high intensity exercise. This stands to reason as runners are normally less fat than walkers.
Also, exercising at a higher intensity induces a greater rate of "excess postexercise oxygen consumption". That is, once you are done with your high intensity exercise, your body continues to consume oxygen and burn fat for up to 3 hours after exercise. Furthermore, exercising at a higher intensity also improves your cardiovascular system.
In summary, while low intensity exercise is a great place to start for beginners, the best way to burn fat, lose weight, and improve your cardiovascular system is to increase the intensity of your exercise when you or your client are able to. You can start by charting you or your client's exercise intensity and continue to increase intensity throughout your exercise plan.
