A "24 hours" badge on a map listing doesn't say whether that means a staffed front desk around the clock or just keyfob access after the trainers go home — a difference you only discover at the door. Every 24-hour gym listed here has that access confirmed from the gym's own posted hours or membership page.

24-Hour Gyms near Ankeny
Good to know
Are there gyms open 24 hours near me?
Yes — many regional and national chains keep at least one location per metro area open around the clock, usually with keyfob entry after staffed hours end. Independent gyms less commonly offer true 24/7 access since it requires either overnight staff or a secure unstaffed entry system.
Is a 24-hour gym staffed all night?
Usually not. Most 24-hour gyms have staff on-site during peak hours — mornings, evenings, weekends — and switch to unstaffed keyfob-only access overnight, with cameras and emergency call buttons standing in for a front desk.
