You should do strength training first. The purpose of aerobic warm-up is to warm up, so it takes about 5 minutes to move your limbs and enter a state of strength in a good state. Generally speaking, the strength is about 6 movements, and each movement has 4 groups. It usually takes 45 minutes to complete the training.

The purpose of aerobic fat reduction is to reduce fat, so the time is 45 minutes or more. But strength first and then aerobic will avoid this situation. Relatively speaking, after 40 minutes of strength (excluding leg and foot training, leg and hip training, if you practice well enough, your legs will get weak when you walk), it is not so difficult to run for 30~40 minutes.

Aerobic exercise refers to the physical exercise carried out by the human body under the condition of adequate oxygen supply. That is, in the process of exercise, the oxygen inhaled by the human body is equal to the demand, achieving physiological balance. Simply put, aerobic exercise refers to low-intensity, rhythmic exercise, which lasts for a long time (about 30 minutes or more) and has moderate or upper-middle intensity (60% to 80% of the maximum heart rate).
