Elizabeth Akinwale is a fitness expert. She has competed in several Crossfit Games and won Regional titles. She is also a mother of two. See more about Elizabeth via her Instagram and website (first 2 links below).
That "after photo" (which is amazing, right? and was taken by Tai Randall - see 3rd link below) is also special, because she won the event (called "Soccer Chipper") at theCrossFit Games in 2015.
If you want some more motivation, see the 4th link to a Before & After photo of her in the gym and at the 2014 CrossFit Games. And if you want both motivation and a giggle, check out Elizabeth and her husband using a wheelbarrow and their kids to create an at-home workout that is tough (last link).
