Elasticity in Clinch

From Coach Jason Webster: Here is a great fight (ca Golden Age of Muay Thai) that is a great example of what we talked about in Saturday's clinch class. To wit, Rajasak in the red corner was a very feared fighter who fought almost exclusively with knees.  Watch him continually "hollow out" his shoulders and chest, move his hips back to knee. Also notice his intense forward pressure that continually expands and contracts "elastically" even while maintaining tight contact with his opponent.
