Default Re: ROCK JAW (Neck & Jaw Strengthener for boxers)

@ Irishny

You have common sense. These guys want scientific proof because they can't comprehend that a bag of rocks with a mouthguard puts pressure on the jaw muscle and strengthens the neck and jaw. Those who want to box and compete with a weak jaw and neck,..that's your choice.

Ya know what...maybe Doc Brown from Back to The Future should do a test on The Rock Jaw. The sales would increase.

Or...I can spar with The Rock Jaw haters and we can find out who has a better chin. I've been using it for 2 months, 165lbs age 39 in Deltona Florida. Lets do the test with some 10oz gloves and no head hear.Mail me and come find me.
