Technique work- Rolling
The roll is one of the most technical movements in parkour, and requires lots of practice. When starting, a soft surface should be found to roll over, such as grass, a rubber playground surface, or similar.
The important considerations are getting your head out of the way, rolling from shoulder to hip, and remaining smooth throughout.
