Lion Killer From The Back Mount - Brazilian Jiu-Jitsu Techniques

From the back mount, take your right arm round the front of your opponents neck. Your elbow should be directly under their chin.

Grab your left bicep with your right hand.

Slide your left hand down the back of your opponents head or even onto your right shoulder. Now push your elbows together to apply the choke. Another way to apply the choke is to pull your shoulders back and take a deep breath in whilst pushing their head forwards.
