Daredevil Oleg Sherstyachenko has posted a video on YouTube showing him performing a morning workout - on a skyscraper.

The clip shows him balancing precariously on an incredibly high ledge as he performs amazing - and heart-stopping - stunts.

The footage, taken by a friend, sees the adrenaline junkie dangling dozens of floors up on the edge of the city skyscraper. It also sees him performing a series of tricks as he teeters on the ledge.
