At the age of 39 and after giving birth to twins, not many women may be brave enough to pose in just a swimsuit. But it's clear BBC presenter Gabby Logan has no need to have any body hang-ups as she looks stunning in these new pictures.

The former gymnast has been revealed as the face of Speedo and models their new Sculpture range, which is designed to nip in waists and flatten stomachs.

It seems Gabby doesn't need the extra help of the flattering swimsuit given her enviable figure and the presenter has admitted the secret of her success is swimming.

She swims at least twice a week and said she loves the 'tranquility' of the sport as well as the health benefits.

'Swimming is the perfect exercise if you want to feel healthy or to just relax – going for a swim always clears my mind and gives me some valuable "me time" when I need it,' she said. 'I like the tranquility of swimming as I can't be reached by phone or email.'

As well as doing lengths in the pool, Gabby also regularly takes her children, twins Reuben and Lois, seven, along with her.

'I love going swimming with my children. We have so much fun in the water and it's great to play and do sport together,' she said.

As the daughter of Welsh international footballer and manager Terry Yorath, Gabby grew up in a sporty environment so she's exercised from a young age. But she said it's never too late for people to get involved in sport - especially if they have been inspired by the London 2012 Olympics - and swimming is one of the easiest sports to take up.

She said: 'Swimming is so accessible. There are thousands of sports centres around the country so most people will have one within a few miles of their home so they are easy to get to. Go along and ask about adult swimming lessons if you don't already know how to swim.'

Despite the health and holistic benefits of swimming, research from Speedo found that it's insecurities about their bodies that's stopping many women from taking up the sport. Over a third of the one thousand women they surveyed said 'the way they look in swimwear’ was the main reason they were put off.

More than half (53 per cent) said they had almost been reduced to tears while trying on swimwear while 48 per cent admitted that they felt too self-conscious to take their children swimming.

Gabby, who is married to former Scotland rugby international Kenny Logan, said she understands these insecurities but she says it shouldn't put women off swimming - as it can make you fitter and more toned.

She said:' We have all felt the unease about getting into our swimwear, but we should be motivated by the sporting achievements from the last few months to get ourselves a little healthier and to take the plunge.'

Speedo hope their new Sculpture range will also help women feel more motivated to swim as their real styles are designed to be flattering and fashionable as well as sporty.
