I'm not saying that being a fitness instructor will eventually require hip replacing. I said that is what happened to my friend. What I have seen is that teaching for a long time, does lead to injuries, no matter how much you try to avoid them. Good flooring, good shoes, yes they help, but over time, teaching 4,5,6 classes a day, which I know some people do, standing all day long. Yes that does play a role in fatiguing the body. and it isn't always obvious right away. Until suddenly something major happens, i have heard of perfectly healthy trainers suddenly throwing out their backs or trying to teach with a taped up sprained ankle, because if they don't teach, they don't get paid. There are no sick days with this job. Because we work on contract, and like i said, no sick days. So it can get hard.

Anyway, enough. Do i have any regrets being an instructor. none. i love it. I have learned a lot about running my business, the industry, i have met wonderful people, and have had wonderful mentors - which i do recommend, find yourself a mentor to help you through this process.
