Tom Jones has revealed that he has become a fan of inversion therapy, which sees him regularly hanging upside down like a bat.

The 80-year-old singer has invested in an inversion therapy frame, which helps prevent back problems and poor circulation.

"In 2030 I am going to be 90 years old," he told The Sun. "I hang upside down. You know, on one of those frames.

"It's great. You put your feet in the thing and you flip and you hang."

Jones added that as part of a new year health kick, he has also hired a personal trainer and taken up boxing lessons.
