Ballet lessons, Pilates classes and yoga routines might seem like an unlikely triumvirate for a rock star to swear by.
But for Rolling Stones front man Mick Jagger, these quiet pursuits have helped maintain a physical peak which belies his near-70 years.
And he is not alone.
Increasing numbers of septuagenarians are acknowledging the importance of a healthy diet and regular exercise to help neutralise life's excesses and prolong their years.
In a recent interview with Q magazine, the singer laid bare details of his rigorous regime, including running several miles a day, swimming, kickboxing and cycling.
Sir Mick said: "I train five or six days a week, but I don't go crazy.
"I alternate between gym work and dancing, then I do sprints, things like that. I'm training for stamina."
Ahead of a show, the rock star - whose band will headline Glastonbury later this month - said his routine involves "bed early the night before, about 2am. Up at 10am the next morning".
He added: "Any earlier, you'll be too relaxed by showtime."
Michelle Mitchell, charity director general at Age UK, said there was no "magic formula" for staying mentally and physically healthy in later life.
She added: "However, a healthy lifestyle that includes regular exercise, a balanced diet and an active social life are all important factors.
"It's vital that everyone in later life has access to the right information and support that enables them to live as well as possible, and that organisations delivering health and care services to older people provide them with regular opportunities to improve their health and age well.
"It's never too late to make small changes that can make a big difference."
