First of all, yes, no problem. But when you get older, you should pay attention to certain exercise methods and step by step. The first is a week's adaptation period to prepare for a lot of exercise. Look at your problem. If you want to get muscle training, you should start with aerobic training within two hours before going to bed, such as jogging, playing table tennis and badminton. Appropriately increase equipment training. Exercising the upper body is mainly barbells and dumbbells, and horizontal bars are also needed. In this week's diet, we should give priority to crude fiber foods, such as celery and leeks. After adaptation training, I usually exercise equipment for three hours and do aerobic exercise for one hour every day. Perseverance is the most important thing. Be careful not to overload training, which varies from person to person to prevent physical injury. Exercise and self-defense. I wish you the best of health!
