Here are the compiled rules of Banned and Illegal Techniques in Combat Sports.

 

I’ve compiled a list of fouls from a variety of combat sports. This is also a list of great techniques and strategies usable for a foundation in Martial Arts. Now, there is a lot of overlap here so I’ve attributed the technique/foul/penalty to the sports where I found it.
