Go on, stiffness is only caused by rapid muscle congestion after anaerobic exercise, which is a good phenomenon. Don't worry about this, but the training should be targeted. Although I don't play basketball, I found him very antagonistic when I watched the game. Many players are thin and simple. If you are heavy and strong enough, you should be flexible and have an advantage in confrontation. In Asia, while paying attention to strength training, we should also pay more attention to coordinated training, and basketball is important for leg strength, waist strength and shoulder strength. The arms should not be too thick, but the waist and legs must be strong, and the chest muscles and abdominal muscles should be used as shields. Moderately developed is good. Skipping rope can enhance coordination. If there are conditions in the gym, it is good to find a regular coach to learn sports in the fitness ball. Paying attention to muscle relaxation and stretching before and after training can avoid and relieve stiffness, and the key point is to combine strength training with coordinated training. You can refer to the strength training materials of foreign basketball, and I believe your skills will be greatly improved.
