Gymbox

This centrally located gym offers some of London's most witty workouts from its 'Tour de Holborn' spinning class to jolly 'Cheerleading' class (pom poms optional). 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. Despite the boxing theme, more than 50 per cent of members are women - the Look Better Naked class is currently a lure. A newer branch in Covent Garden (at 42-49 St Martins Lane, WC2) boasts a vast studio and Olympic-sized boxing ring.
