At the top of a skyscraper with a million-dollar view, what is billed as Asia's most exclusive fitness club opened last month - but only 999 members will be invited to join.
Gravity is Fitness First's response to a survey of more than 2,500 senior executives in the Lion City who reported wanting a "more exclusive and bespoke" wellness space.
And for those who pay a joining fee of S$3,000 (HK$16,500) plus S$600 per month, Gravity certainly delivers.
Personal coaches and nutritionists will monitor the fitness, sleep and stress levels of the chosen few - invites are currently being issued to big corporations and chief executives - and on-site doctors will assess health and use blood tests to devise bespoke vitamin programmes. Regular 3D scans, which use 400 data points, will track members' body shapes.
The 17,000 sq ft facility on the 38th floor of CapitaGreen tower, in the heart of Singapore's central business district, has an infinity-edge swimming pool with views of Indonesian islands and an aerial yoga deck that looks out to Marina Bay Sands.
An app will discreetly rank members in terms of progress - "We think members will be competitive by nature," says Simon Flint, chief executive of Fitness First Asia - and advise which dishes at the on-site restaurant are best for their body type. There are also meeting and conference rooms, so executives can slip business in between their morning swim and lunchtime yoga class.
If the S$9.5 million venture is successful, Flint says, there could be plans to launch Gravity in Hong Kong and London.
For Hong Kong executives who can't wait, Gravity is accepting members from the city.
