Thanks Ghost. As far as destructions are concerned, I don't think it's so much a matter of will or pain tolerance, as it is the physical destruction of the bone(s). I'm thinking that you are thinking of a different type of destruction than what I am referring to. The type I'm referring to is when you point the cap of your knee directly at the center of the person's shin. For the person who is throwing the kick, it would feel like shin kicking a telephone pole. I've had people throw kicks at me (in training) with no power, but they didn't stop them in time, and they nearly broke their leg as a result. In fact, Demi Barbito did this once and actually did break his leg. I've also seen a few videos of this happening on the internet. As far as elbow destructions go, it's the same principal. You put your elbow(s) in front of your face, and when the person throws a punch, you cover with the elbow, allowing the punch to run directly into it. The person throwing the punch would feel like he had just punched a brick wall. In a street fight I was once involved in, this actually happened. He threw a right cross at my face, and I used an elbow destruction on his fist. I actually felt the bones in his hand shatter. When he hit my elbow, instead of his hand bouncing off of it, it kept going. I actually felt his closed fist feel soft and mushy.
As far as ranges go, I do train in all of them. My question regarding proper kick timing was just referring to the long range aspect of it. I wouldn't do very well in the closer ranges if I didn't survive the long range first!
Thanks again
