I have paid different amounts of money for various exercise things at various times. Things I do not regret: this summer, a lot of money on a yoga studio in Mexico City, when I could go 5–6x a week. In grad school: a couple of months of cross fit because it was a great community. Things I kind of regret: money I spent at ok gyms but never went to. I think it’s more about evaluating your life, your budget, and whether or not you will go to a thing.
