Getting out on the water and doing some stand-up paddleboarding can give you the chance to burn hundreds of calories in a hour for a great workout.

Now imagine doing it for 4,050 miles across the open ocean.

That’s what South African big-wave surfer Chris Bertish did. Bertish started his trip three months ago from the Agadir Marina in Morocco and arrived at English Harbour in Antigua in 93 days, became the first person to cross the Atlantic Ocean on a stand-up paddleboard.

"Across the entire Atlantic Ocean and I am finally here," Bertish wrote on his Facebook page. "I don't need to be strong and keep it together any longer; it's been 93 days and it's done and I let it all go... I am home!"

Bertish wrote that he averaged around 40 miles of paddling per day. He told The New York Times that he encountered some rough weather—and sharks.

“You can feel very inconsequential at sea,” said Bertish. “It’s the only thing that’s going to help you survive out there for that amount of time. That said, there were definitely times when I was hanging on by a thread, just trying to keep it together.”

 

Stand-up paddleboarding has grown in popularity over the past few years and after a feat like Bertish’s, it only should get even more attention. SUP—as it’s known for short—can give you a true all-around workout. “The reason so many people are drawn to paddleboarding is that it’s an amazing full-body workout that improves your core strength, cardio fitness, balance, and flexibility with virtually no impact,” Cody White, a certified PaddleFit instructor and co-founder of Finger Lakes Paddleboard, told Men’s Fitness.
