Billie Faiers struggles to do a plank as son Arthur, 3, climbs on her back during workout

She often litters her Instagram with bikini-clad snaps showcasing her incredible figure. 

And Billie Faiers was determined to keep up her fitness routine during isolation as she took to Instagram on Tuesday to share a snap of her workout.

But the Mummy Diaries star, 30, struggled to hold her plank after her son Arthur, three, thought it would be fun to climb on her back.  

Billie, who was clad in leopard print leggings and a black top, captioned the shot: ‘The reality of training from home’. 

The mum-of-two was doing the workout with husband Greg Shepherd while Zoom calling her sister Sam and personal trainer. 

Billie also took to Instagram to share a throwback snap from her pregnancy after being tagged by Ferne McCann for the show your bump challenge. 

The reality star posted a picture of Ferne kissing her bump while they were on holiday. 

She wrote: ‘thanks for the nomination @FerneMcCann’, before tagging three other friends’. 

The workout comes nearly a week after the series finale of Mummy Diaries. 

In the episode Greg was not wholly impressed with the first draft of her gown for her Great Gatsby-themed 30th birthday. 

The former TOWIE star’s dress fitting left Greg’s jaw on the floor ahead on the party, as he insisted her ‘a**e’ was out while she commented the reason it was showing was because it ‘was white’.  

Billie looked sensational at the party where she was clad in a dazzling gold gown, which she had custom made with matching gloves and a headdress.  

While trying on her gown, an astounded Greg stated: ‘You can blatantly see your a**e!’ 

As the camera then swapped to the confessional, the businessman said to the camera: ‘I told the guy who’s making it “she’s not walking around with her a**e hanging out”. 

Billie then said the problem with her dress was her derriere was not tanned as they hadn’t been on holiday – and not the fact she was baring all.
