"Being Molly's mom is the greatest joy I've ever known," she captioned the pic. "However, I've learned over the past 4 months that my time really isn't my own anymore and that can make it difficult to do things for myself — like working out."

However, Ali, who gained 40 pounds during her pregnancy, is determined to get back to her pre-baby weight.

"I knew I wanted to make fitness a priority. Not just because I wanted my pre-body body back (although that was definitely a motivator), but because I want to be as healthy as I can so I can live as long as possible to be here for Molly," she added.

The 32-year-old beauty welcomed her daughter this past July with fiancé Kevin Manno, 33.
