Watch this man with no legs set a world record for running on his hands

Zion Clark set the Guinness World Record for running the 20 meter on his hands. His time was 4.78 seconds. Clark, 19, is also an accomplished wrestler.

From Guinness:

[Clark] was born with Caudal Regression Syndrome, a rare condition characterized by abnormal development of the lower (caudal) end of the spine. 

"In my case, my birth mother did not take care of her body at all while she was pregnant with me, she was on a multitude of different drugs, and that caused me to have defects," Zion shared.

"It made my life harder from the get go because I had to go through two different surgeries for my back, just so I could sit up straight." […]

"Nobody is going to get to that top level if they don't put in the work. I'm willing to put in the work and willing to make the sacrifices."
