I think I have the answer to part of the puzzle of how it works, but I don't have the grip strength nor the forearm conditioning to really test it and pull off, and that's just for one technique where I'm trying to get my hand into position to grab. Here's what I know from experience.
1. I know if I get it wrong my arm takes a beating
2. Because of weak hands if feels like my fingers nails are trying to grab and hold on vs my fingers locking the grip.
3. I only feel comfortable working on the outside, which means I have to stand a certain way in order to have an opportunity to grab the punching hand.
4. I feel as if I try to work the inside of the arm, that I'm going to get punched with the other hand. I have no Trust in the technique because I'm too scared to "man up" and get hit in the face if I get it wrong. Normally it's not a big deal but in this case, my head would be wide open.
5. I have a bad habit of "chasing hands" that I need to get rid of. This is where the person becomes so focused on trying to grab a hand or arm that they leave everything else open.
Learn to clinch. Because then the arm stops moving. It is almost always shoulder to wrist because the shoulder moves more slowly.
