New Dongdaqiao gym Muscle Dog is big and aggressive, sure. But its psychedelic IMAX-size spinning screen and wide range of classes, including popular Les Mills Body Combat and Martial, help it stand out in Beijing’s (over-saturated) gym scene. Cyclists are taken on quite the ride via a 270-degree screen – the only one of its kind in China, we’re told – in a workout program called ‘The Trip.’ Muscle Dog merch is even available to purchase on site.
