Would you pay £10K a year to get a body like Tracy Anderson?

I am perspiring profusely. Not the moderate sweat of running for the bus or sitting in the sun on a balmy day. We’re talking droplets making their way down my temple and into my ear, a drenched sports bra, some genuine concern for my hydration levels running through my head. Beyonce’s Ya Ya is thudding out of the speakers, and I realise that while I may still technically be in London, fitness entrepreneur Tracy Anderson has successfully parcelled up her West Coast vim and vigour and delivered it to a subterranean series of marble-bedecked rooms in Surrenne, a wellbeing and longevity members’ club that’s opening in Knightsbridge on April 14, with annual membership at £10k, on top of a joining fee of £5,000.

Tracy Anderson is one of the few fitness pioneers who’s nearly as famous, Jennifer Lopez and Olivia Wilde. She came to prominence in the early Noughties, where pictures of her walking down the street alongside a sweat-drenched Madonna were common tabloid fodder.
