Swiss Olympian Fabian Bösch has social media users asking, "How'd he do that?"
Bösch posted a fun video to his Instagram account on Monday that's gone viral with more than 210,000 views.
The skier held onto an escalator with his right hand and walked slowly along side the escalator until he was lifted off the ground. He rode the escalator to the top with one hand.
Bösch captioned the post: "After 20 years I still couldn't figure out how this thing works! Am I doing it right?"
One user, jaegerbombb91, commented: "Nice arm tuck #perfectform"
Bösch pulled his body up and crawled in between an opening in the railing once he arrived at the top of the escalator.
