If you can, go swimming, so as to keep fit and lose weight without hurting your joints. If you like, run and climb the stairs; If time is tight, use the bed or furniture to do push-ups or sit-ups two hours before going to bed, even if it is a horse step. The key is persistence. Pay special attention, two hours before going to bed. Don't get excited after exercise. I can't sleep at eleven o'clock, and the liver meridian is still noisy, which is not worth the loss.
