While this isn't precisely the same thing, Beth, your story brought up an experience I had an an aging athlete (who was once obese, so I get it) when I was trying to learn a kayak rollover technique. I appreciate the inspiration and will write about it. Your article underscores the implicit bias that too many fitness pros have, which I might posit stretches over into ageism as well. Just because someone has been trained to be an instructor doesn't mean they should instruct, for they carry their issues right into class and display them for all to see and experience.
