In my case, it made me hate exercise. I couldn't do the things they required (stuff like somersaults, jumping the pommel horse, etc.) so I just took an adversarial angle. It was not something to enjoy, but to try to beat if possible, or escape otherwise.

Many years later, I can kind of enjoy exercise like running or swimming but I still never go to gyms as they give me bad feelings.

Indeed, being a teacher myself today, I'd rate my gym teachers as terrible, as setting goals (like somersaults) with little relation to the actual exercise most people do, and more relation to innate talent than effort, while not providing much motivation or explanation of why that is useful (I still don't see why today), seems like a huge pedagogical failure. But I had various gym teachers and they all seemed cut from the same cloth, and other people with similar age and country give similar descriptions. Maybe it's better in other countries or it has improved by time, I don't know.
