KOBOX

Boxing never looked so glam at KOBOX – the flashy night-club inspired studio in Chelsea that offers a fast, furious – but fun – sweaty HIIT class combining heavy bag sparring and functional strength building. In the 50-minute session, participants alternate between a speedy punching routine by numbers that flash up on a wall – or a serious bout of floor work that ticks off everything from squat jumps to lobbing medicine balls at a target. The studio, which is open seven days a week, also keeps a stylish stock of fitness kit and their own branded wraps for sale, plus freshly-made protein shakes to refuel post-workout. A second branch can be found in the City (85 London Wall, EC2M 7AD).
