As for the mouth guard, I have literally chipped every tooth in the front part of my mouth, yet I still am not smart enough to wear one regularly. I don't like the way it constricts my breathing. I'll use it for takedown sessions, but for the most part, they are annoying.
I am amazed. I have been grappling consistently for almost a decade and my nuts have never felt in danger.
Oh, and you guys saying you like cups because they make your subs better need to learn to do Jiu Jitsu without weapons.
don't get how you guys are getting your junk smashed all the time, I've never worn a cup and never been seriously hit in the nuts
I wear cups in tournaments, not at all in training, never mouthpiece.
