The first thing I noticed when Karissa started wrestling other girls is that 90% of them were headhunters. I am not sure if this is because they were not comfortably shooting or if they were taught to go for the headlock. After I saw this I went right to work teaching Karissa how to defend the headlock. You will never see Karissa try to throw the headlock.
As for leg riding Karissa just learned this from her Middle school Coach and she loves to do it because of the diff. moves she can work off of it. Personally I would rather see her try a bar arm half first before going to something else.
As for Coaching, Karissa is treated and coached just like the boys are but just because she responds to this kind of coaching does not mean they all will. In fact she probably gets pushed a little harder then the boys and she responds to this real good.
