Every week, the "Gold Coast Granny Grommets" meet to surf waves and age gracefully.

“We've got a group of about five of us that come every week without fail and get in the cold water regardless of the temperature,” says surfer Caroline Holliday.

Surfing in their sixties, they understand the benefit of being active.

“I think you have to make it a priority, everyday. So, for me I train everyday in some way or other and this is just a really, good, fun way of doing it,” explains surfer Lesley Vick.

“Having that connection is very, very important. It probably outweighs the physical, though that's really important too,” says Holliday.

Beyond the clear physical advantages, researchers suggest that working out in a group can play a crucial role in encouraging older adults to maintain long-term activity and can also help prevent feelings of loneliness.

“The social support and being with others increases our mood and our mental health as well. So, it ticks two boxes if you can get out, get active and get active with others,” says Dr Stephanie Alley of Central Queensland University.
