Sarah Stage made international headlines during her pregnancy for posting photos of her body on Instagram.
Stage showed off her well-defined abs well into her pregnancy and even days before giving birth.
The part-time model gave birth to a baby boy on April 14th.
"James Hunter (4/14/15) 8.7lbs/22 inches of HEALTHY baby," wrote Stage on Instagram.
Then just days later she posted a photo of her post-birth body.
"4 days post baby," wrote Stage. "Total pregnancy weight gain was 28 pounds. I'm excited to resume my workouts in 5 weeks!!"
