After giving birth to twin boys Cy and Bowie last year—and gaining 70 pounds in the process—the new mom is showing off her post-baby body in a picture of her wearing one of her old costumes from Guardians of the Galaxy. The actress wrote on the pic, "Holy S---! You guys, I had to share this. This is one of the old #guardiansofthegalaxy costumes that I wore back in 2013. After twins I can't believe I was able to slip into this," she added. "It pays off to work hard! I mean it mommies of the world, if I did it you can too." Zoe Saldana on Motherhood, Embracing Her Curves, and Why She Can No Longer Stand Heels Saldana has been very honest about her struggles to work out and get back into fighting shape. Since giving birth, she has been sharing workout selfies and videos of her at the gym not only to inspire herself, but her other "fellow mommies" out there. She has also posted diet and fitness tips as well as very honest notes about her "slow ... painful ... and frustrating journey" towards getting back into shape. Way back in April (her sons were born in November of 2014), Saldana wrote on Facebook, "Bouncing back feels impossible, but I know it is important as a woman, and now a mommy, to not give up. I am determined to get my energy back and find balance for my body before these little guys start walking, and before I go back to work..... my clock is ticking!" Her posts have been filled with thousands of comments from fellow mothers praising her for being so honest like in July when she shared this gym selfie. When her picture was met with thankful comments, Saldana wrote, "Beautiful ladies, thank you for your positive comments. You have no idea the joy and pride I feel when I read your comments saying you feel inspired and want to do it for yourself. Please continue to share, I was inspired by so many mommies around me to get back into shape because they shared their journey with me. We are stronger when we stick together- wishing each other good, cheering each other along." PHOTOS: Relive Zoe Saldana’s Best Maternity Style Moments Well the cheering worked! Saldana looks great!
