Age, as the saying goes, is just a number.

Yet new data published today (October 1) suggests that most seniors in the UK don't follow the old adage, at least with regards to physical exercise.

A survey commissioned by leisure operator, Everyone Active, revealed that 78 per cent of over-65s were not achieving the amount of weekly activity advised by the NHS, which includes 150 minutes of aerobic exercise and two days of strength exercises.

In response to this, Everyone Active has launched a campaign hoping to breathe new life to the saying by offering free gym access to over 65s.

The Cheam Leisure Centre, David Weir Leisure Centre in Carshalton, Phoenix Centre in Wallington and Westcroft Leisure Centre have all signed up for the Age Is Just A Number campaign.

As such, they will be offering a free gym or swimming session to everyone over the age of 65 between Monday October 28 – Friday November 1.

"It’s our aim to create friendly, welcoming environments that motivate people of all ages to get active.

"I would urge older generations to take the opportunity to visit our centres free of charge with a friend and discover all different ways they can enjoy getting active," said David Bibby, managing director at Everyone Active.

"This research proves there is still a lot of work needed to improve activity levels among people aged 65 and over in the local community," he pointed out.

The leisure operators are also on the search for a ‘face of older people’s activity’.
