Ladies have got the stomach for raising vital cash.
Since first catching the belly dancing bug in 1997, Lynn Flounders of Marske has taught scores of ladies the exotic Egyptian art.
Now, Lynn and her fellow dancers have shimmied their way to raising pounds 1,100 for the Great North Air Ambulance.
Lynn, 66, runs classes each Friday morning at Redcar's Durham Road Community Centre.
The first classes are for individual Egyptian belly dancing, while the second part of the sessions are for group-based American "tribal dancing."
A few times a year, Lynn also organises a hafla - a belly dance party where everyone dresses up and wiggles the night away.
And it's the proceeds from a hafla, along with a sale of costumes, which makes up the air ambulance donation.
Mum-of-two Lynn, a retired shorthand typist, says belly dancing's an exotic and fun way to keep fit.
She first saw it at the Whitby Folk Festival and from then on, she was hooked.
"It was so unusual, that's what I liked about it at first," she said.
"It was difficult to work out how it was done. People think you just wobble everything, but I've learned there's a lot more to it than that!"
