SINGAPORE - Members of a popular gym chain in Singapore were told on Monday that one of its two gyms will close in seven weeks' time.

In two e-mail messages sent out to members, the management of Pure Fitness said its gym at Knightsbridge in Orchard Road will close on Dec 15 as part of a reorganisation plan for the site.

The gym, together with other tenants in the building, is handing back the space to the landlord to make way for Singapore's first Apple store in 2016.

"We understand that this is short notice but we have only recently been informed of the handover date on this site," one e-mail said.

Pure Fitness also has a gym at Asia Square in the Marina area. The Pure group also runs Pure Yoga at Ngee Ann City and at Chevron House.

It added that more classes will be added to its facilities at Asia Square and Ngee Ann City.

The management said it is also opening a new yoga studio in the Central Business District in the second quarter of 2016, and is "hoping to finalise terms on another gym location to open in late 2016 as well" in the Orchard area.

Other tenants in Knightsbridge include CIMB Bank and fashion retail stores Tommy Hilfiger, Topshop/Topman, Abercrombie & Fitch and Brook Brothers.

When contacted, Ms Nurul Huda, a customer service officer at Pure Fitness' Knightsbridge outlet, confirmed the gym's impending closure and said it will "definitely compensate" customers on a case-by-case basis.
