(Right handed speed vault) Ill try and break it down for you! When you are approaching your obstacle make sure you leap with your right leg, as you are about to leap from your right leg your left leg should be going into the air. After your right leg leaps make sure it comes under your left leg! You will be landing with your right leg first. As soon as you leap from your right leg your hand should be coming into contact with the obstacle! It is best to use your hand/arm to correct your axis and push you along your way! Try and make sure that you land so that you are back into your running position!
