If you don't warm up enough, you will start practicing directly before you get used to it, resulting in elbow injury. Do aerobic exercise before practice. Aerobic exercise will speed up blood circulation, leading to congestion in the elbow during practice and squeezing into some soft tissues. The elbow joint is too weak to bear the weight you use. The long head of triceps brachii is sore, and the long head of triceps brachii will pass through the elbow, so elbow pain may be a problem of three heads. The solution is not to do aerobic exercise before practice, warm up more, and stretch three heads after practice, which still hurts, indicating that your joints are too weak and need to be strengthened slowly. It's all advice. It hurts every time. It's better to see a doctor.
