16-year-old smashes 111 concrete blocks with his head

While most 16-year-olds are accused of being hardheaded, Taekwondo champion is quite literally so.

The Bosnian teenager broke an astounding 111 concrete slabs in just 35 seconds using only his head to set a new Guinness World Record. What is perhaps more remarkable is the technique the youngster employed to accomplish the feat.

Ahmetspahic back flipped into the record books via 16 columns of concrete blocks. Considering the strength and agility required to successfully complete a regular back flip, it seems almost unfathomable to throw in the element of breaking blocks with your head mid-flip.

Despite the degree of difficulty, the only thing Ahmetspahic didn’t appear to break was a sweat.
