Who said a baby changes everything?

Just four months after giving birth to her son, Sutton Joseph Tennyson, new-mom Angela Simmons was back in the gym and hitting the treadmill hard. Now, all that hard work has paid off because Simmons recently shared a photo of her svelte figure in a bikini while on vacation.

Check out the pic below:

Need a little words of encouragement? Here's what Simmons had to say to ladies around the world:

" What they fail to tell you is that you will never be the same after you have a baby .. you actually just become stronger." #WelcomeToTheNewMe #Onit #GreatWorkOutThisAm @itscoachnelson @supremeteamboxing !!! Thanks for building me up 💪🏾💪🏾💪🏾

Sweet!
