One of the greatest athletes the world has ever seen, Bo Jackson was the first to successfully play both professional baseball and professional football. The two-sport star had a relentless training regimen that led to the creation of the Nike Training line.

Just a few of his memorable sneakers include the Air Trainer 1, Trainer SC I Trainer SC II and the Air Trainer TW, which is proof that Bo knows.
