Gymbox

This centrally located gym offers some of London's wittiest workouts from its 'Tour de Holborn' spinning class to the jolly 'Lady Gaga' class. Located underneath High Holborn, this compact space combines the atmosphere of a nightclub with state-of-the-art facilities. A full-size boxing ring dominates the main space, along with a large movie screen. There's also an impressive free weights area, spinning studio and two exercise studios. While the boxing theme might suggest a macho environment, more than 50 per cent of members are women. A newer branch in Covent Garden (at 42-49 St Martins Lane, WC2) boasts a vast studio and Olympic-sized boxing ring.
