It took Mark Jordan one year to train for an astonishing new world record and just one day to break it.

The 54-year-old Jordan has been recognized by the Guinness Book of World Records as the world record holder for most pull-ups in one day. Jordan completed 4,321 pull-ups, breaking the previous mark by more than 100.

For Jordan, his achievement shows that people are never too old to hit the gym.

“This is about a message that it’s important to be able to take care of your health in many ways, no matter what age you are,” Jordan told the television station KRIS-6. “The benefits are something than can not only help you but allows you to be able to provide guidance and inspire others as well.”

Jordan set the mark in November 2014, but the Guinness Book of World Records didn't certify the mark until Monday.

Throughout his training and during the actual event, Jordan was raising money for a charity called HELP, the Hammons Education Leadership Program.

As for why he stopped at 4,321, Jordan says the consecutive nature of those four digits would make the number easy to remember.

The previous record was 4,210, set by Australia's Caine Eckstein in October.
