The Luxury Wellness Members’ Club: Surrenne Four floors beneath the busy streets of Knightsbridge lies Surrenne, the longevity and wellness members’ club at newly opened The Emory hotel, which is reinventing the premise of the membership model and, in spite of its busy urban location, is as serene as it is scientific. Sign up to be a member and you will have access to wellbeing on tap, including a dedicated doctor (with functional diagnostics ranging from cardiovascular and hormone tests to microbiome mapping), a juice and food menu developed by nutritionist Rosemary Ferguson , a Tracy Anderson workout studio, and a state-of-the-art gym (complete with longevity-specialised trainers) and spa. The devil is in the detail here, with points of note including the lap pool, with an underwater soundsystem that will play podcasts or meditation music to your preferences, as well as the neuroscientist-curated music throughout the space that is clinically proven to induce calm and is AI-created, so that you never hear the same beat twice.

There’s also Alice Temperley-designed robes that go up to size XXL (a particular bug bear in the historically non-inclusive spa industry), hyperbaric chambers, contrast therapy in the form of a snow booth and hot sauna, an interactive yoga studio with a floor-to-ceiling screen (allowing for resident trainers to dial in and teach from all over the world), plus all manner of spa treatments that you could wish for. And this is just the beginning. Wit.
