Two Canadian brothers are making a splash on social media — literally. The Nova Scotia duo are pushing winter fitness to the extreme by regularly jumping into freezing cold lakes.

John and Brad Mayo — both in their late twenties — were both once champion kayakers.

Now, the brothers run an Instagram with 50k+ followers that showcases their insane winter training.

According to their website, the Mayo Bros aim to help "men and women unlock their physical and mental potential" through calisthenics, which is exercising using only your body weight.

The Mayo Bros combine it with regularly jumping into freezing Canadian waters — or, as it's more professionally known, cold exposure therapy.

Because there's nothing like a little refreshing dip after your afternoon skate.

Or drinking your morning coffee while submerged in a freezing ice-covered lake.

Canadians aren't strangers to freezing cold temperatures — Newfoundland recently spent a week navigating through snow tunnels — but the Mayo brothers' winter fitness routine is more than impressive.

People everywhere are in awe of their polar dips.

"I want to want to do this. I just don’t want to actually do it," one woman wrote.

"You're a beast and an inspiration my friend," another person said.

Aside from people dog sledding through a Tim Hortons driveway, the Mayo Bros might just be the most Canadian thing to come out of Nova Scotia yet.
