I think everyone has their own teaching methods and styles. It is inappropriate to criticize colleagues' teaching quality, because it may affect their self-esteem and self-confidence. Everyone has different skills and knowledge in fitness field, so we should respect each other. ? On the issue of the hard pull range before and after squatting, the half-way movement does have limitations, but it does not mean teaching garbage. Everyone's physical condition and ability are different, and the coach needs to adjust the training plan according to the actual situation of the players. Full squat and hard stretching may cause excessive pressure to some people, while half-way exercise can better protect joints and reduce the risk of injury. ? The key is to find a training method and plan suitable for each member. As coaches, our duty is to ensure that members can achieve fitness goals under the premise of safety. Therefore, instead of criticizing our colleagues, we should focus on how to improve our teaching level and communication skills in order to provide better fitness services for our members. ? Finally, I want to share an inspirational quote with you: "Respect others, respect yourself and respect the cause of fitness." Let's work together to provide better teaching for members and create a harmonious and positive fitness environment.
