Thirty Seven Degrees

Although almost entirely underground, this fitness club on the banks of the Thames has such great facilities that you can easily forgive the lack of riverside views. Five studios offer classes ranging from yoga to circuit training, a golf simulator, boxing ring and a state-of-the-art gym with brand new AMT (a cross between an elliptical trainer and step machine) equipment. The urban feel is increased by the presence of a new Beauty Essence salon, juice bar, walk-in GP service, steam room, sauna and solarium. The club also caters to the corporate market with classes and treatments aimed at the time-poor (do a 15-minute exercise class at lunch) and lucrative company rates. It also has a branch in Kensington's Olympia.
