Anahi promptly resumed her exercise regime, and her hard work is paying off as she has already regained her pre-pregnancy figure.

The proud new mum took to Instagram on Sunday (05Mar17) to share her excitement at her post-baby slim-down, posting a snap of herself in the gym, wearing an all-black sports bra top and leggings.

In the caption, she appeared to refer to her toned figure after giving birth as she wrote, "Back! 1 month, 2 weeks and 3 days. Trying it again!"
