In fact, when you find that the coach's contact with you is wrong from the beginning, we can subconsciously choose to avoid it. What does this mean? For example, today's class is squatting to practice your hips, and the coach took this opportunity to touch your waist. At this time, when he comes into contact with you, you can avoid it or pretend that you are not stable. This time is actually showing that you already know his intention, but you also explicitly avoided it.
If the coach is still stubborn at this point, go on. Next time you touch your body, you can cough loudly. Oh, speak up. If the coach doesn't do well, he will feel nervous and scared. Usually he stops at this time.
If he still doesn't repent after this, just say it directly and express it to him euphemistically first. If he has a greasy attitude, express it directly and loudly, or even tell the gym owner to let him handle it. After all, you have gently reminded him many times!
Don't think about forbearance in this situation. Forbearance only helps others. We must learn to say no loudly!
