Taking to Instagram on Monday, she shared candid before and after snaps of her progress in the three weeks since she initially took up the challenge on July 6th. 

Sporting a black gym vest and matching underwear, Danielle looks notably slimmer while giving followers a look at front, side and back shots of her body.

Captioning the images, she wrote: ‘During my pregnancy I put on just over 4 stone (yes I did take full advantage of eating what I craved and wanted but if you can’t when your pregnant when the hell can you).
