Cancer Claims Man's Leg, Doesn't Stop Him From Doing Backflips (VIDEO)

Most people can't do a backflip with two legs.

Adam Starr, a 21-year-old cancer survivor, posted the video below to his YouTube profile, and he will blow you away as he flips all over the place. But surviving cancer is only half of it. Adam lost his leg to the disease.

The video below is Adam's first time back in the gym since the amputation in 2009.

Undoubtably, Adam is an inspiration for overcoming adversity and getting back into the swing of things after such a traumatic experience.
