Elizabeth Akinwale is a fitness expert. She has competed in several Crossfit Games and won Regional titles. She is also a mother of two.
That "after photo" (which is amazing, right? and was taken by Ricardo Merigo Salado) comes from the 2014 CrossFit Games.
If you want some more motivation, see the 4th link to a Before & After photo of her climbing the rope in practice and winning in competition. 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).
