It just depends on how creative you can get with the equipment at your disposal.

I assume people go to other gyms either for coaching, Olympic powerlifting, ancillary amenities (pools, bball court etc) or specific shit like crossfit. Or they just want higher quality equipment to work with.

But for people just trying to get in better shape PF gets it done. I'll always keep a membership solely because theyre EVERYWHERE and I travel a lot
