Tell me more about the sternum shot.How do you aim it? How do you execute it properly? How do you train it? And what should be the effect on an opponent of a sternum shot properly executed?
The sternum shot I think he's tlaking about would be aiming for the solar plexsis, which is right under where your ribs end in the center of your chest, right above your stomach. Feel that soft spot? Punch yourself there as hard as you can and you'll see what he's talking about.
Also, I agree that Throat strike >> Nut strike lol
