When people with sub-health and weak constitution exercise, they should first set reasonable and scientific exercise goals. Exercise should be mainly moderate aerobic exercise, such as yoga, walking, jogging, qigong and so on. The time for each exercise should not be too long, and it is best to control it within half an hour, mainly depending on their physical acceptance. In the afternoon, they feel that they can't hold on, so they can have a rest.

Exercise time is also more important for people with sub-health and weak constitution. If it is summer, you should choose a cooler time to exercise. If it is winter, you'd better choose a warmer time to exercise. We must persevere and not rush for success.
