Carol Vorderman works out famous bum as she reveals EXACT training for those curves

Carol Vorderman has revealed her gym routine - and the exact way she builds up her famous bum.

The former Countdown star, who went viral last month when pictures of her supposedly new pneumatic curves emerged, was forced to deny having secret butt implants, insisting her figure is 100% natural.

And she showed off exactly what it is she gets up to in the gym in a series of snaps taken by her personal trainer, Dave Concannon, who works out with Carol three times a week to maintain her figure at 58.

Sharing the pictures on Twitter , Carol wrote: "Early gym with Little Dave dave_concannon ....he always says 'Never miss a Monday' so I don't....LOLOLOL LOTS of glutes with weights today at NuffieldHealth ....ouch."

In the snaps, Carol wore a tight black long-sleeved top and Lycra yoga pants that clung to her body.

She finished off her fresh gymwear look with a pair of bright pink sneakers and kept her long blonde hair loose.

The maths whizz told her Twitter followers that she loves working out her glutes and legs and stretching out her back and hamstrings in the gym.

She was pictured reclining on one piece of equipment while pushing an enormous 20kg weight away from her, telling fans it was "double ouch".

And the third set of pictures showed her working her abs and core muscles by bending over a padded seat and crunching her way up to a standing position.

"And my favourite machine...could stay on this one for hours....MAHOOSIVE stretch thing....Bliss," she captioned the shots.

Her trainer Dave applauded Carol for her hard work, tweeting her: "That's the one Carol. Be persistently consistent and consistently persistent. Good work. Big Love from Little Dave x."

Carol also revealed her usual breakfast consists of a cup of tea and a Ryvita with butter and marmalade as followers bombarded her with questions about her healthy lifestyle.

It comes after she insisted she'd had no plastic surgery to create her gravity-defying curves, telling the Mail's You magazine: "I promise I haven't had bottom implants... I've been working out for decades, so the shape of mine is down to years of keeping fit."

She attributed her ample assets to genetics and the HRT she went on to get through the menopause - with the added bonus of a raging libido.

Carol revealed that she has plenty of options for a little sexy time, saying: "I have a number of special friends but I’m not doing anything wrong. Everyone's single. And yes, apart from one, they're all younger than me."

She added: "I don't want to settle down. I’m enjoying my freedom."
