'Not tensing ... tensing .. just letting u know... I take loads of pics of myself and then choose one I think I look alright in,' she wrote beside the snap. 

'Did warm up strength and hiit and abs and stretch... felt a bit flat working out today (might be a bit homesick) but still glad I did it.'

The star has been posting several shots of herself taking part in her own '30 day fat burn' regime, detailed in her fitness DVD.

The star has been posting a variety of shots on her social media during the show's fourth series which features Lydia Bright, Bradley Wiggins and Louis Smith among the contestants. 

On Sunday, she modelled her warm undergarments with a super sassy pose ahead of the launch of the show. 

The presenter, 49, certainly looked ready for the icy cold temperatures of the Austrian ski resort of Kühtai in her black thermals.

Posing in a pine doorway in what appeared to be a cosy lodge, Davina placed one hand on her hip and touched the top of the door frame with the other.

While she was well wrapped up for her time in the mountains, Davina paraded her envy-inducing six-pack for a sporty cover shoot for the new issue of Fit & Well magazine.

Flashing her incredible abs as she posed in a tiny tangerine sports bra, the TV presenter admitted she trains 'like a maniac' in order to maintain her jaw-dropping physique. 

The mother-of-three - who raises daughters Holly, 15, and Tilly, 13, and son Chester, 10, with husband of 17 years Matthew Robertson -  teamed her crop top with bright cobalt workout leggings as she worked her magic in front of the camera.

Speaking to the fitness magazine, the former Big Brother host admitted she does occasionally fall off the wagon just like the rest of us.

Davina explained: 'Last summer, we’d had an amazing time away with the children and I got back and thought my jeans felt a bit tight. I’d put on 6lb in two months.

'The weight always goes on my bum and my thighs. All I could think was I had to get into the dress for This Time Next Year and look exactly the same as I had done a year ago.'

But the fitness fanatic managed to shed the pounds thanks to her 'training like a maniac' and enforcing an even healthier meal plan.

Davina shed 4lbs in a matter of weeks thanks to her diet tweaks, which included granola for breakfast, salad for lunch and protein for dinner.

The Jump presenter has incorporated a healthy lifestyle into her life so much that she even encourages fitness dates with her husband of 17 years.

She said: 'We love sharing a hobby together. We don’t have to motivate each other to exercise – whether that’s going out on the bikes or to the gym together – because it’s become part of our lives.'
