Anaerobic exercise and aerobic exercise are two different types of exercise and have different effects on the body. Anaerobic exercise is mainly to enhance muscle strength and endurance, such as weight lifting, squat, push-ups and so on. , can increase muscle mass and metabolic rate, help to reduce fat and shape. Aerobic exercise is mainly to improve cardiopulmonary function and endurance, such as jogging, swimming and cycling. , can accelerate fat burning and waste metabolism, and help improve cardiopulmonary function and physical fitness.

According to the timetable you provided, it may not be the best choice to do anaerobic exercise from 4 pm to 5 pm and start aerobic exercise at 8 pm. This is because anaerobic exercise mainly exercises muscle strength and endurance, and muscles need a lot of energy during exercise, so it takes some time for the body to recover and adapt after anaerobic exercise, which may take several hours or even longer. If you do aerobic exercise immediately after anaerobic exercise, you may increase the risk of physical fatigue and injury, because your body has not fully adapted to anaerobic exercise.

In addition, aerobic exercise at night is not necessarily the best choice. This is because aerobic exercise can make the body generate heat, increase the heart rate and respiratory rate, which may affect the quality of sleep, especially at night. If you do aerobic exercise at night, it may affect the quality of sleep, because the body needs a period of time to cool down and adapt.

To sum up, if you want to do anaerobic exercise and aerobic exercise at the same time, it is best to do these two exercises at different times of the day. For example, do anaerobic exercise in the morning or afternoon, and do aerobic exercise in the evening or evening. This can avoid the risk of physical fatigue and injury, and can also better exercise all aspects of the body. Of course, the specific exercise time and arrangement need to be made according to your personal situation and exercise goals.
