Celebrity personal trainer Steve Halsall has opened a 3,500sq ft (325sq m) boutique health club in a co-living building in north-west London.

Enrgym, in Old Oak, Willesden, is free to use for people living in the complex, which has been developed by property company The Collective using a 'co-living' concept described as "a new way to live".

The design of the building focuses on bringing people together through its communal kitchens, dining rooms and lounges, as well as its cinema, sports bar, library and roof garden.

Halsall, who has trained comedians, pop stars, actors and film directors, said: “With Enrgym I’ve used my 20 years of experience listening to customers on what works and doesn’t with gyms, and I’ve tried to create the perfect environment for our customers.

“In partnership with The Collective, we’re now looking to expand to other sites in the UK.”

The gym, which has 18 pieces of cardio equipment and 20 multi-use and free weight stations, offers personal training and holds yoga, HIIT, and spin classes.

There is also an onsite café offering protein shakes, healthy snacks and nutrition advice.

For those not living in the property, membership is £34 (US$46, €38) for a standard pass and £49 (US$67, €55) for full membership, which includes classes. Gym goers can also opt for pay as you go.

Halsall received support from NatWest for the project. It relationship manager, Ian McCormack, said: “Steve has an impressive vision and the experience he brings, alongside his team, means the future looks very bright for Enrgym.”
