A man in the Philippines just jumped his way into a new Guinness World Record.
34-year-old Ryan Ong Alonzo completed 40,980 double-unders in jump rope in 12 hours.
There was a moment of panic when Alonzo suffered cramps about halfway through his attempt, but he managed to bounce back and finish.
"Double-unders" involve the rope passing beneath the jumper twice for each jump.
Alonzo said he banked on his previous marathon experience to get him through the long day.
