When life deals you lemons, you make lemonade.
In Zach Anner's case, when life gives you cerebral palsy, you make work out videos on YouTube. Zach is hilarious and is a great source of motivation by showing what kind of adversities can be overcome.
Zach also wrote a book, If At Birth You Don't Succeed. Once you get over the awkwardness of Zach's cerebral palsy, you'll find that he's hilarious.
