The arm drag from the clinch is is easily one of the most underrated and underused techniques in MMA or wrestling. I first started using this technique a few years back when I was watching some Russian wrestlers takedown their opponents over and over again with this setup.
The easiest way to teach this is from the over-under clinch, but it can work from pretty much any type of clinch.
How to arm drag from the clinch (assuming his right arm is the underhook):
- Sit your hips back and push his wrist down with your left hand.
- Now that his arm is off of you, pass his arm across your body slightly.
- With your left arm, grab the back of his shoulder.
- Twist your body hard, and reach around his back with your left arm.
