Go for it!!!!  Most of the teachers at the rec center that I have belonged to for so long are almost as old as I --- and definitely, fit (and have to be certified to teach).

Only a very few have stopped teaching over the years....

Thanks retiredtraveler for taking the time to respond.  You are absolutely right.  I think my choice of words were not the best.  I'll see if I can modify my post.  You are correct, teaching most types of fitness in some situations is not a profession that provides a living.  I simply want to teach to make a difference.  I was wondering more about the experience of transitioning into doing something like this at midlife, get some 'heads up'  and  the process of selecting a good institution.

Thanks much and have a wonderful week. Peace

This may be a cynical answer, but I don't know anyone that has made a 'profession', and a living, out of teaching any types of fitness class. I know a number of teachers, personally, having worked out at a local gym for 25+ years and talking with the instructors over the years. Everyone I know (and I'n not an employment guru, of course) teaches classes part-time and makes a bit of spending money, but not a living.

   Maybe it's different in your part of the country, but it's even more difficult now as gym and various health-related businesses (such as yoga, martial arts, etc.) have seen greatly reduced business.

   Not trying to be negative ---just be sure you're realistic. For you, your best bet is to find instructors in your own area that can tell you how business is rather than checking on people from other parts of the country.
