Some individuals only want to do low intensity exercise because they feel it is the best way to burn fat, therefore making it the best way to lose weight. As a result, these individuals avoid moderate or vigorous exercise.
The American
Council on Exercise details why this “fat burning zone” at low
intensity exercise is a myth. Low
intensity exercise, by definition, is anything less than 40% of VO2 max.While the highest percentage of fat utilization comes from low intensities, ACE explains that the “total
amount of fat burned is actually lower at low intensity compared to higher
intensities for the same duration". The optimal “fat burning
zone” occurs during moderate to high intensity (55-72% VO2 max) because of
greater total calories being burned leading to a higher percentage of fat being
burn.
A study by Achten, Gleeson, and Jeukendrup proves it is not necessary to only exercise at a low intensity claiming “fat oxidation rates are high over a large range of intensities”. Wu and Lin support high intensity exercise for weight loss stating, “it’s a better choice”. Individuals should aim for moderate exercise intensity when trying to burn fat.
High-intensity exercise has become increasingly popular as more people recognize the benefits of cranking it up several notches. Contrary to common belief, long, low-intensity workouts aren't the only way to get fit. Too many times you see people just walking on the track or tread mill to get a workout. Then you hear them complain that they see no results. It has been to my understanding that the more you sweat the more you will lose fat. I don’t want to bash the people who are slowly getting into the routine of being active, but don’t complain when results are bare to nothing. The bottom line is get your butt up, and sweat your you know what off! Great topic.
