The name stands for “Functional Training 45”, with sessions being a mix of functional HIIT and strength exercises delivered in a 45-minute format. Each day, the workout is predetermined by F45 HQ and is the same at every F45 location across the world. 

Their Saturday “Hollywood” sessions are the only 60-minute class and are famous for hiring local DJs to create a party atmosphere and bring the community together.

Workouts are typically run by two or more coaches per class. To support the coach, clients are guided by screens that display each exercise as well as beeps and graphics that cue you to work, rest or move to your next station.
