The centre, operated by Everyone Active in partnership with Ealing Council, put on family activities on Saturday (May 9) and raised £200 for the Anthony Nolan Trust, which helps save the lives of people with blood cancer.
More than 3,000 visitors took part in a range of sports including swimming, inflatable fun in the pool, Zumba, indoor cycling and virtual classes in the new spin studio.
There were activities for children including gymnastics, taster swimming sessions, street dance and a bouncy castle.
Everyone Active general manager Amar Varsani said: “We are incredibly grateful to all of those that came and made the day a huge success.
“We were delighted to see so many of the local community taking part in activities and having so much fun and proud of the money we raised for the Anthony Nolan Trust, which is a really worthy cause."
The latest equipment to be installed following the revamp includes treadmills, elliptical cross-trainers, upright and recumbent bikes, Adaptive Motion Trainers (which allow you to walk, run, climb and lunge) and Concept 2 rowing machines for cardio workouts, and the kit also has screen consoles and full internet browsing.
The strength and resistance area has been enlarged with abdominal and back machines, resistance training systems, super benches, heavier dumbbells, a power cage and an Olympic bench press.
A virtual group cycling studio with a simulated instructor will also take participants through their paces on a giant screen.
