Your abs will hurt just watching this insane display of core strength

In the latest episode of Skiers Do The Weirdest Workouts, a Canadian world champion and Olympic silver medallist takes centre stage.

Kelsey Serwa demonstrated her incredible core strength with a workout video posted to Twitter, with the 28-year-old reigning WinterX Games champion jumping from exercise ball to exercise ball.

Careful, your abs might feel sore just watching this.

Straight up ballin' 😎

And while Serwa’s workouts are obviously super impressive, teenage freestyle skier Andri Ragettli’s is also worth a look.

Now we just have to hope for a collab.
