Lazy Vault - parkour guide
This is the most relaxed vault you can do. You can practise it from ledges, rails and walls.
A lazy vault is, as the name implies, a slow movement and is often made from a standstill or walking pace over the obstacle. It is an easy and elegant way to move over an obstacle. This exercise is performed by approaching the obstacle from a slightly crooked angle, placing your preferred arm on the obstacle and individually setting off with your legs (the leg closest to the arm in position) and then using the back arm to grip the body so that your buttocks don’t hit the obstacle.
