For most people, doing an advanced yoga pose like the "lotus" is extremely challenging, but for 83-year-old Bette Calman, getting into the position is a cinch.

The Australian yoga instructor has more than 40 years of teaching experience under her belt and is showing no signs of slowing down, London’s Daily Mail reported.

“You're never too old,” Calman told the newspaper. “The body is a remarkable instrument. It can stretch and stretch, and get better all the time.”

Calman is the author of three yoga books including one called, “Yoga for Arthritis.”

“I'm proof that if you keep at it, you'll get there,” she told the Mail. “I can do more now than I could 50 years ago.”

And Calman is keeping at it — teaching up to 11 yoga classes a week.
