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.
Serwa, who won a silver medal at the 2014 Winter Olympics in Sochi, has got into the habit of posting some of her more interesting workouts.
Using #WackyWorkoutWednesday the freestyle skier has been showing off her skills for quite a while.
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.
