Proper physical contact can help students master the movement posture more correctly and correct the incorrect training posture. For example, the coach doesn't give proper physical contact, and the students who just started training can't even lift the lightest arm equipment in the gym. At this time, the coach is often needed to support part of the weight of the equipment. At the same time, when students make posture mistakes, they should correct them to avoid unnecessary injuries caused by their later training mistakes.

Besides, gyms are basically monitored now. If the coach has inappropriate physical contact or even sexual harassment with female students, the woman will naturally not submit to humiliation.
