Do Less Intense Workouts Burn More Fat?

This show originates from this is show 61

Heart Rate ZoneI've heard that exercising at a less intense pace it burns more fat. Burning at an intense rate burns more sugar. This is true. According to you burn “Low intensity training burns about 50% fat for energy while high intensity training burns about 40% fat for energy. This is not a huge difference.

Say, for example, walking for 20 minutes burns 100 calories. Then 50% of 100 calories is 50 fat-calories burned.

Now say 10 minutes of high intensity interval training burns 160 calories. Well, 40% of 160 calories is 64 fat-calories burned.

BOTTOM LINE: I spent some time exercising at 56% to 70% of my maximum heart rate and still broke a sweat. So if you can only workout at that pace – DO IT. Remember 60% of your maximum rate is still more calories than you will burn sitting on the couch.

Calculating your maximum hear rate

Take your age and subtract it from 220. So for me (I'm 43 for a few more days) that would be 220-43 = 177. That is my maximum heart rate.  If I want to exercise at 60-85% of my maximum heart I do the following:

Multiple 177 by .6 = 106 beats per minute. This is the lowest my heart should beat during exercise.

Then I multiple 177 by .85 = 150 beats per minute.  So I can st my heart rate monitor to beep when I go below 106 and beep if I go above 150 beats per minute.  I use the Polar F6 heart rate monitor (they also have a ladies version)
