If you're serious, go somewhere else. Health club etiquette breach. No rules or no rules posted (monopolizing equipment): clothing & gear left on equipment to hold if they plan to use it later. Standing around socializing, talking about how hard they're going to party, how much they'll be drinking. Sit on equipment and rest while others wait to use it.
Theft: Don't leave a smart phone on the life-cycle or other equipment. I started reading on my hard spinning. Came back and it was gone, so was the loud woman on her phone, next to me that just walked in a few minutes before and immediately left with my phone. Staff didn't offer to check cameras (if there are any) to help recover it. Phone cost more than the 2 year membership.
Sanitary (lack of): -Members leave bottles & paper towels all over littering. -Men's bathroom; immature members pee all over the seats. Staff don't check it regularly.
Equipment maintenance: Equipment falling apart and not repaired; noisy equipment; missing pins & D-Hooks, not replaced
