Formation of fat
The body will store excess calories in fat cells, and these cells have no upper limit. As long as you keep eating fat cells, they will keep getting bigger.
Fat consumption/sweating
It is not that the more you sweat, the more fat you burn. 84% of the fat is high consumption of carbon dioxide discharged through breathing, and most of the rest is discharged through liquid as water.
Optimum fat combustion formula
When the best heart rate is reached during exercise, you can enter the body fat function mode, (220- age-static heart rate) *60%-80%+ static heart rate, and keep this heart rate for 30-45 minutes. Remarks: 60%-80% is an interval, not a reduction of 80%.
