Are all gym amenities available 24 hours a day?

Main cardio and weight equipment remain accessible 24/7, but full-service amenities like pools, saunas, day care centers, and smoothie bars usually close overnight. Check individual club schedules for exact amenity cutoff times.

How much does a 24-hour gym membership cost?

Standard monthly dues range from $15 to $60 depending on the brand and location. Most chains also charge a one-time key fob fee of $10 to $30 upon enrollment, alongside a recurring annual facility fee of $39 to $49.
