British Olympian Louise Hazel has created a new workout session inspired by erotic novel Fifty Shades of Grey.
The 29-year-old will teach a one-off '50 Shades Ass Whopping Workout' in London next month, which will include "ropes, chains and pain".
"I read all three books and I just didn't want them to end, so I designed a workout involving chains and ropes in honour of all young women like me who want to live vicariously through Anastasia Steele," the Daily Star quotes Hazel as saying.
"It's going to be gruelling, but there will be more pleasure than pain as ultimately the ladies will be satisfied and feel really good about themselves afterwards."
Hazel is reportedly due to appear on Channel 4 reality skiing show The Jump.
