Another part of the Motor Moron series.
There was some confusion about how to go about rolling in 8 directions. This video should clear that up.
Basically there are 3 types of rolls here. Straight forward (and backwards) somersaults. Diagonal rolls commonly done in martial arts and parkour. And then the sideways roll. All are pretty easy to do and can be done with a little practice.
All these basics can be expanded upon for further body awareness, control and skill. I recommend you check out Tumbling Illustrated for more details.
