On a corporate level, they are scam artists. I submitted proper paperwork to terminate my membership in October 2020, noticed they continued to bill me through January '21, and when I called to notify them of the error, they claimed they never got the paperwork. I filled it out in the gym. I don't live in Illinois, I had no reason to not cancel the membership. They "Lost" the paperwork and stole money from me for 3 months.
The gym is fine, but go somewhere where they won't scam you.
