Ryan Thomas has lost a stone in six weeks with the help of his fiancée Lucy Mecklenburgh.

The former TOWIE star, 36, took to her Instagram stories on Wednesday night to share a video of Ryan working out and lifting weights.

Lucy, 28, explained that he’d been able to shed the weight thanks to all his hard work in the gym and with a little help from her fitness plan Results With Lucy.

At the start of the video Ryan is down on the floor doing press ups with a weight in each hand, with Lucy captioning the video: “Stolen my PT!”

The next video was Ryan laying down on a bench as he lifted weights.

A proud Lucy stood in front of her man as he pumped iron.

She said: “This is how he’s lost a stone in six weeks!”

Ryan made grunting sounds as he lifted the weights up and down.

“He’s been working really hard,” Lucy added.

She captioned the video: “On round 6!!!

“Very proud of him! Losing 1 stone in 6 weeks!!”

Lucy and Ryan have both lost weight recently.

She gave birth to their son Roman in March and has already lost the four stone she gained during her pregnancy.

The new mum explained that she lost the weight not by jumping on any fad diet bandwagons but by eating three squares meals a day.

Lucysaid on Instagram: “I eat three balanced meals a day, lots of water when I breast feed and a few snacks e.g. oat cookies, hummus, rice cakes, half an avocado.

“I do lots of walking and light exercises & stretches on @resultswithbump. And I’ve lost 4 stone!”
