Winter Olympic hopeful Andri Ragettli set pulses racing months before the Pyeongchang showpiece with a mesmerising display of agility in a training video.

Ragettli, 19, is hoping to compete in South Korea, having won gold in the Slopestyle/Big Air category of the 2015-16 Freestyle Skiing World Cup, as well as sealing fourth place in the overall standings.

Used to hurling himself through the air in sub-zero conditions, Ragettli looked a picture of cool calm as he tumbled across a gymnasium in a video posted on Twitter.

Will it be the perfect preparation for Pyeongchang? Only time will tell.
