Video: Extreme bungee jumpers attach hooks to their skin
This is definitely not one for the faint hearted.
A group of extreme Russian bungee jumpers have pushed the limits on an already daring activity.
The fearless 'Russian Sinner Team' took the plunge from a 250-feet platform with only four deep skin piercings in their backs to support them.
Bungee cords were attached to the piercings to create a rig capable of supporting their entire body.
And, if that wasn't enough, the adrenaline junkies filmed the moment that the bungee cord snapped them backwards by the skin causing excruciating pain.
Watch the video but be warned, this is not one for the squeamish.
