Grandmas are often the unsung heroes of strength and endurance, but Donna Jean Wilde from Southern Alberta is taking that to a whole new level! Move over, playground boasts about whose dad is tougher—Wilde just casually smashed the world record for the longest female plank, clocking in at a mind-boggling four hours, 30 minutes, and 11 seconds. That’s longer than some people spend binge-watching their favorite TV shows!

If you’ve ever tried holding a plank for even a minute, you know it feels like an eternity. It’s right up there with waiting for your food to heat up in the microwave when you’re starving or enduring any amount of time running (let’s be real, it feels like forever). So, hats off to Grandma Donna for proving that age is just a number—and apparently, a world record-breaking plank time!

Next time you’re in a playground-style argument about whose grandma is tougher, just remember that Grandma Donna could probably out-plank them all without breaking a sweat.
