F45 is Australia’s fastest-growing franchise – and the latest international fitness craze to arrive in Beijing. Centered around high-intensity 45-minute workouts, the circuit sessions are aided by TV screens that demonstrate how to perform each exercise. There’s plenty of up-tempo EDM and high-fiving, but the session coaches are very encouraging and allow you to take things at your own pace. Expect to leave extremely sweaty. WeChat: F45Training.
