Andrew Shapiro's quest to set a Guinness World Record began seven months ago, with American Ninja Warrior and his father's cancer diagnosis.
Shapiro, a fan of the obstacle course challenge television show, decided he wanted to dedicate himself to getting into peak physical condition. Inspired by his father's five-year battle against colon cancer, the 17-year-old practiced incessant pull-ups with the goal of setting three world records during a Relay for Life event in Fairfax County, Virginia.
Beginning Saturday at 8 a.m., he started his pull-up marathon. Within six hours, the Langley High School junior completed 3,515 pull-ups - a new world record. By 12 hours, he had finished 5,742 pull-ups - another world record. Then he set his sights on a final record - the most pull-ups performed in 24 hours: 6,800 completed by Czech Republic athlete Jan Kares in 2015.
At the 15-hour mark, Shapiro matched Kares' 24-hour record and kept going. After 18 hours of pull-ups, Shapiro stopped, having put his chin above the bar 7,306 times. His family set up three video cameras to continuously record Shapiro's attempt while 15 judges observed his efforts and completed paperwork to certify the achievement for the Guinness World Records books.
So how did Shapiro do it? He credits his success to American Ninja Warrior, the Star Wars movies, sushi and pineapple.
