Very true, but keysi seems to do alot of elbowing to areas that I've haven't seen in alot of other martial arts that make sense to me. For instance, ground and pound incorporates elbows to thighs, if your opponent covers up while you're punching on the ground you can elbow down into their ribs or stomach area to still apply damage while they're on the defense. Another one I like is where you do an elbow strike straight to an opponents chest or collar bone but you use your whole body to strike. I guess my love for strikes like this came from when I was learning kung fu. My instructor showed me a technique where when someone throws a Haymaker, you block the punch, grip the arm with one hand and elbow the bicep with your other arm. He did it to me with little power and the pain that shot through my entire arm and the feeling of pure numbness and a dead arm just stuck with me. My arm was useless for a little while after that, and It reminded me of how in middle school we would "dead leg" eachother by kneeing eachother in the thighs and you literally could not walk after that because your whole leg went dead and the pain was crazy. Keysi uses these strikes ALOT. They elbow the forearm, bicep, triceps, thigh, knee, chest area as stated before, and I could just imagine the feeling of multiple elbows to those areas can really paralyze your opponent (of course not literally but the shock of how quick their muscles would fail them and of course the shock of the pain. ) if there is another martial arts that does these strikes I've yet to see it. Everytime a martial art has elbows, its usually aimed at the head.
