The 37-year-old "Guardians of the Galaxy" star shared a picture of her wearing the catsuit from the film saying she has successfully achieved her goal, reported E! online.
"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.
"@marvel and @jamesgunn don't be mad, I'm not showing anything that hasn't been seen before... Besides, aren't we designing new stuff?.... It pays off to work hard! I mean it mommies of the world, if I did it you can too," Saldana wrote.
In the past one year the "Avatar" star shared various diet tips and fitness regimes as as well as videos of herself hitting the gym on her Facebook page.
