On the upside, they have a lot of equipment, services, and classes. They offer it at a great price and the hours are convenient, however for working 3rd shift the classes I would want to do aren't offered early enough for me.
Downside was offered a free hour of personal training when I signed up. Once the personal trainer found out I had no plans to continue personal training, they had no interest in me and were very dismissive.
The BIG Downside and reason I'll never go there again. The only payment they accept is automatic withdrawals from my checking account/credit card. Was going out of state for a few months and wanted to cancel my membership. Went in and they refused to cancel it there... even though I signed up there. They stated I had to fill out a form and send it to the California office. Sent it out and was still getting charged. Repeated the process. Still got charged. After the third time and me STILL getting charged, closed my checking account against them.
Then they had the nerve to threaten to send me to a collection agency for not paying the bill. I stated they could go ahead, I'd be happy to take it to court and get my money back for the months of them billing me after I initially tried closing the account. Found out later, LA Fitness has a policy that anyone who tried to close the account and doesn't send it certified mail, they just throw the letters away. I know they've had a few class action lawsuits against them, and can't remember if this was one of them.
