An enterprising Kiwi mum has a high profile fan in Kate Middleton, after creating a fitness programme then turning it into a business.
Kelly Rennie created the Busy Mums Programme after she returned to Nelson from the UK with her five-month-old daughter Neveah.
"I was a single Mum, with a five-month-old. And I didn't have a job," Ms Rennie explains.
Unable to afford a gym, the enterprising mum decided to turn Facebook into a gym.
"But it works better than a gym because people don't need to go to a gym, they can do it within their own home. And I think that's the most exciting part," she said.
Ms Rennie knew she was on to a good thing when her programme got the royal seal of approval, after receiving a letter of thanks for sending a fitness guide to Kate Middleton.
"It was official, with the official royal stamps, it was her just saying a personal thank you. For us it meant she'd actually looked through it.
"She'd possibly taken action with it. So yeah, it was a real honour," Ms Rennie said.
The recognition proving that getting healthy and happy can simply be a case of keeping mum.
