Kobox, Marylebone
Best for: Fight Club-meets-nightclub vibes
While the mere thought of a high-intensity boxing class has us
seeing stars, this snazzy gym takes things outside the ring, with a
50-minute session that sees a combination of bag-work and hardcore
HIIT. By that, we mean six-punch combinations and breathers that
look like burpees and bicycle crunches – all made worth it by a
whooping calorie burn (promise). The vibe? Industrial interiors
embellished with neon LED lights, dancehall soundtracks and the
sort of instructors that will push you beyond the limits of what
you thought possible. Classes will set you back £22, and there are
Kobox clubs in Chelsea and the City, too.
