I only have a little time to exercise every night, 10. When you come back from the evening self-study, eat less when you go home at night, or you will be hungry and can't sleep. You can practice your grip strength after eating. It is not suitable for strenuous exercise after 10 in the afternoon. Because the working time of the liver is 1 1 to 1, you should go to bed before 1 1, but doing exercise before going to bed will reduce the quality of sleep. When approaching sleep, you should avoid strenuous exercise, sweat a lot, and be excited before going to bed. Excessive body temperature will reduce the quality of sleep. Before going to bed, you can relax your muscles through massage and yoga, and do some stretching and relaxation exercises to promote sleep. Grip strength mainly stimulates the muscles and internal blood vessels of the arm, which has little effect on appetite unless you breathe in your stomach. So, you can get up in the morning to do some warm-up and then do a small range of strength training.
