It all began 30 years ago when Rosnah Jonet installed mirrors in the hall of her home and converted it into a studio to teach aerobics. It may not sound extraordinary – but then Rosnah, better known as Kak Rose, just celebrated her 75th birthday last month and all her students are younger than her.

“My oldest student is 74 and she’s been learning with me for 30 years. The rest are in their 60s and have been with me more than 20 years,” says Kak Rose, who lives in Ipoh with her husband.
