Sharing a video of herself in her underwear, she wrote: ‘I can’t believe how just by changing my breakfast and leading a healthier active lifestyle I’ve managed to lose 21Ibs and gained 7Ibs of muscle.’
Revealing the secrets to her transformation, Danielle continued: ‘I work out 2-3 times a weeks for an hour at the gym and I still enjoy going out at the weekends for dinner and a few drinks.
‘I haven’t shared this pic to try and impress or create attention but to only help you ladies realise this is something I would never had posted 16 months ago.
Before adding: ‘I’ve never felt so body confident and happy in myself.’ Good on you, Dan!
And with her new found confidence, the former TOWIE lady has been showing off all her hard work on Instagram, because why not?
So, as Danielle continues to flaunt her gym-honed figure, we’re taking a look back at the star’s VERY impressive makeover.
