This centrally located gym offers some of London's wittiest workouts from its 'Tour de Holborn' spinning class to the 80s-flavoured 'Voga' 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. Further branches in Bank, Farringdon and Westfield London.
