Disclaimer: the full name of women-only gym fit4life is ‘fit4life girl power studio.’ If you’re still reading, hear us out. The Jianwai SOHO gym offers 50-minute workouts (with a focus on circuit training, core, toning, weights and dance) taught by friendly teachers in a pleasantly designed space. fit4life differentiates itself from basically every other gym by being unabashedly feminine. Classes are named ‘Dance Like Beyonce’ and ‘Beach Body Sculpture’. The decor includes a big inflatable pink flamingo and beach deck chair. It’s fabulous, though admittedly may not appeal to all. In that case, we suggest Muscle Dog in Dongdaqiao (the antithesis of fit4life).
