The variety of people working out.........ages, sizes, race etc.
It's all moot now because of the pandemic, but I get upset when someone sits on a machine for many minutes, NOT working out, but looking at his/her phone. I'm sure if you asked them, they'd say, "I only looked for two minutes", but I've watched.........it can be more like five to ten minutes.
I know it's a good place, but after joining, I was injured (not at PF) so did not go. We moved and I was not close enough for convenience. Basically, I paid the entire time, but did not go. The only reason for the "9" is because you do not accept canceling over the phone, even when I moved out of the area.
