Brothers break Guinness record for climbing stairs with someone on their head

VALENCIA, Spain (KGO) -- Two men from Vietnam have broken a Guinness World Record for the most consecutive stairs climbed while balancing a person on their head.

The two brothers ascended the ninety steps of Saint Mary's Cathedral in Spain in just fifty-two seconds.

The pair has been rehearsing for the attempt at the record for fifteen years. Guinness posted the video of the men on YouTube, calling it an "extraordinary display of core strength and stability."
