On an empty stomach in the morning, the glycogen storage in the body is low. Doing aerobic exercise at this time will increase the energy supply ratio of fat and decompose more fat.

However, aerobic fasting needs to pay attention to two points: the intensity should not be too large, and the heart rate should not exceed150; The time should not exceed 50 minutes, and it should be controlled at 30~40 minutes.

Principle: If the intensity of aerobic fasting is too high, glycogen storage in muscle is not enough. At this time, protein in muscle will supply energy through a lot of gluconeogenesis, and then muscle will be lost and metabolism will be reduced. It is not easy to gain muscle, so cherish your muscles. In this way, muscle and fat are lost together, and the body is easy to automatically save energy, and the calories consumed during non-exercise will be reduced.

Note: people who are prone to hypoglycemia and poor health, or those who are dizzy and flustered after aerobic exercise on an empty stomach and have no state all day, do not do aerobic exercise on an empty stomach.

Then do aerobic after fasting aerobic VS strength, which fat decomposition efficiency is higher?

This involves the energy supply form of muscle glycogen and the transformation of lactic acid.
