Managed to get those blunt fakies on lock? Then let Josh 'Manhead' Young talk you through the backside variation...
For the Backside Blunt, it's pretty much the same principles as Blunt Fakie, apart from when you ollie out, your shoulders should always be turned away when you are in blunt. It is a fluid motion from ollie out 180 and in backside, and committing and rolling away.
You go up with enough speed to get into a blunt position.
Turn your shoulders away from the backside. Body should already be turning away.
Ollie and out, leg should follow your shoulders. Land in, all your wheels plus the coping, and roll away.
