Polish low-cost operator CityFit is expanding its portfolio with the addition of two new sites in Warsaw and Poznan.

Exact details of the clubs have not been confirmed, but work is currently underway at both sites and the clubs are expected to open by "late autumn".

As well as the new openings, CityFit has revealed plans to "evolve its facilities" by introducing a full-service gym experience across its 15-strong portfolio of clubs.

The chain will embark on an extensive refurbishment programme of its existing gyms, remodelling interiors to incorporate new features, such as relaxation zones and lounge areas.

CityFit has appointed design agency Zynk to undertake the improvements.

"We've worked with zynk from the inception of the brand," said Ewa Morawska, CityFit's operations and administrations manager.

"We worked together to create a distinctive interior personality that communicated the pioneering concept of the budget gym, which was new to Poland at the time.

"Now our service is evolving slightly, we need the expertise of Zynk to ensure there is a consistency between all of the sites.

"In particular, when it comes to revamping our older sites we want to be able to incorporate the new areas into existing footprints without compromising our customers’ experience."

Since its launch in 2014, CityFit has rapidly established itself a leader on the Polish low-cost market.
