I’ve been part of a fitness group here in California for the past 1.5 years. It’s called Boot Camp, and I have no idea why! Anyway, most people in the class are 25-30 years younger than I am and have been part of this group for several years. I don’t lift weights as heavy as theirs and I can’t always keep up with them, but I had felt confident that I was holding my own (except when jogging, which is the one place where I consistently lag far behind them). I found a way to be okay with this, to enjoy working out with them, without thinking I should be as strong or skilled as they are.
