If you lift heavy weight you jaw clench. That makes your jaw muscle grow.

Bro science lol - I clench my teeth with no weight in my hands(& crack teeth/crowns etc)! I've cracked 3 wisdom teeth, crowns etc(now I need the cubic zarconian crowns b/c I break everything) Id suggest a mouthpiece!

He definitely just made that up. Where jaw muscle is concerned, chewing is going to do a lot more for growth than clenching during lifts. And most people naturally open their mouth when lifting, to breath and grunt.


But that's not even what this thread is about, since we're talking about bone growth.
