Re: ROCK JAW (Neck & Jaw Strengthener for boxers)
LOL I'm still having trouble understanding why some of you think strengthening the neck and jaw muscle is not important for taking a better punch.Jaws get broken because the jaw muscle is weak. This is all common sense. Arm wrestlers strengthen their forearms so they can have a strong arm right??? Why don't some of you who do not do any forearm exercises try to arm wrestle a tournament arm wrestler and watch how fast he pulls you down.
