Hello, the length of exercise depends on the way and intensity of exercise.

Usually after 30 minutes of aerobic exercise, you will burn fat to get energy. Therefore, in order to achieve the goal of losing weight through aerobic exercise, the time of moderate and low intensity aerobic exercise should not be less than 30 minutes at a time. And every time you do strength exercises, the main consideration is its load intensity. Take 60%~70% of the maximum load, 8~ 12 times as a group, and do 2~3 groups each time.
