1, whether aerobic exercise is effective in reducing fat depends not on exercise time, but on heart rate. Only when the heart rate reaches 65%-75% of the maximum heart rate will the body consume fat to the greatest extent. An hour of aerobic exercise, if you can't reach the fat burning area all the way, actually won't consume much fat at all. Although I sweat a lot and am very tired, I actually consume sugar in my body.

2. Recommend a good method to reduce fat. Do strength training first, then do aerobic exercise, so that not only the heart rate can quickly enter the fat-reducing area, but also the sugar in the body will be consumed by strength training, forcing the body to break down fat to provide energy. So as to achieve the effect of reducing fat.
