A 93-year-old woman, who can still strike the perfect pose, has been crowned the oldest yoga instructor in the world by Guinness World Records.

Tao Porchon-Lynch is also a dance competitor, and even though she will turn 94 in August, she is still as vibrant as ever.

"I'm going to teach yoga until I can't breathe anymore, then I'll just fly away to the next planet ... I love yoga, it brightens my day and makes everybody smile," Porchon-Lynch said.

Tao won't give any of her secrets away, if indeed she has any.

She has been teaching professionally for 61 years, although it was only at age 73 that she decided to focus solely on being an instructor.
