Andrew Shapiro is a 17-year-old junior at Langley High School in Virginia. He attended a Relay for Life event last weekend in support of his father who has been diagnosed with colon cancer. At the event, Shapiro set his sights on the Guinness World Record for most pull-ups in 24 hours, and he ended up shattering three records, including the one he had set his sights on.

From the Washington Post:

“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.”

Here’s the video proof:

Smashing the 24-hour world record in 18 hours is absolutely ridiculous. Congratulations Andrew!
