Serena Williams Has Wasted No Time Getting Back in Shape

We really shouldn't be surprised that a serious athlete like Serena Williams is quick to get back in shape after having a baby. But in just two weeks?! That's crazy!

The 35-year-old professional tennis player and her fiancé, Alexis Ohanian, gave birth to their first child, Alexis Olympia, on Sept. 1, and it appears that Williams has wasted no time in getting back to the gym. The highly decorated tennis star posted to Snapchat to show off her progress, already fitting back into her pre-pregnancy clothes. We're seriously impressed!

In the mirror selfie, Williams poses in a pair of shorts, captioning the image: "Back in my jean shorts 2 weeks..."

Williams's quick recovery was undeniably aided by the fact that she kept up her exercise regimen while pregnant. "I intend to keep exercising for as long as possible while pregnant," she told The Telegraph back in August. "I want the baby to be healthy and for that you need a healthy life."
