Hilary Duff feels like a new woman after hitting one of the major goals she set for herself a year ago.

The “Younger” actress went on Instagram on Tuesday to share her excitement that she is finally back to her pre-pregnancy weight ahead of her daughter Banks’ first birthday.

“I have been working really hard to get back to my pre-baby body before Banksy turned a year! It was my goal…and I did it!” Duff wrote on a workout photo shared to her Instagram Story.
