James Peterson is a veteran fist-pumper. In fact, he may be the world’s best. Peterson recently fist-pumped for 17 straight hours in the hopes of setting a Guinness World Record.

The 34-year-old from Ohio said that this isn’t the first time he’s gone on a fist-pumping marathon, but it is the first time that he’s had it documented.

Peterson said:

“I did this on St. Patrick’s Day but it was not documented… I used to hang light fixtures so I am used to having my hands above my head.”

The Slideshow reports that Peterson used superglue to make sure that his hand remained in a fist throughout his attempt.

Peterson started fist pumping on Friday morning and ended his world record attempt at about 3 a.m. on Saturday. Peterson was followed by two videographers during his attempt and the tape has been sent to Guinness.

Peterson doesn’t know if he’s in the Guinness Book of World Records yet, but the book of world records does have quite a few fist-pumpers throughout its pages. In 2010, 5,726 people set the world record for most people to fist-pump in one location.

Are you impressed by Peterson’s strange world record attempt?
