The heart is around 50 to 80 beats per minute at rest and maximum rate is 220 minus their age. For example, for a man of 35 years, his maximum heart rate is 220-35 = 185 bpm.
To burn fat, it is necessary that the body draws its energy from fat. And this is possible when the heart rate is around 60-70% of the maximum frequency. For our example is: 65% x 185 = 120 bpm.
Therefore this man of 35 years, eliminate fat when undertaking physical
exercise that will lead to having an average heart rate of 120 bpm.
This is quite low as heart rate. It will be a little hot, and will hardly breath.
But the advantage is that after 30 minutes, the body will draw its
power directly in fat, and that this intensity, it may extend the period
for a long time ... 1:30 say!
