1. communication and understanding: have a frank dialogue with your son to understand his motives and ideas. Understand what he thinks of his father and why he should fight against him through fitness. According to your son's specific situation and background, you can give him more specific advice and support.

2. Establish a healthy parent-child relationship: If there are family problems or tension, solve the problem through family therapy or counseling. Fitness itself can't solve all family problems, but establishing a healthy, mutual understanding and supporting parent-child relationship can ease conflicts and help sons deal with their father in a healthier way.

3. Emphasize the purpose of fitness: help my son understand the real purpose of fitness, not only against his father, but more importantly, pay attention to physical health, enhance physical fitness and maintain a healthy lifestyle. He can realize the multiple benefits of fitness and regard it as a way of self-improvement, and he will treat fitness more positively.
