Hey all..hoping to help all of you fighters strengthen your neck and jaw with my product,The Rock Jaw . Works great for anyone in the fight game. Can purchase on ebay or website. $5.00 + shipping. You insert the mouthguard,let rock bag hang and lift your head up and down for repititions. The weight of the bag puts pressure on the neck and jaw muscle. Strengthens very well. www.rock-jaw.20m.com
lol...it's a tethered mouthguard with a weighted sac hanging off it? If you sell any of those, you're a genius. My hands free spider killer did not sell quite as many units as I had hoped. This content is protected
hello, what you think guys about neck rotations? http://www.youtube.com/watch?feature=player_detailpage&v=K9TC0-mC6iM#t=481s
After reading the initialpost, then seeing that guy bending over like a toothless hick with a racoon hanging out of his, and laughing non stop for the first 5 minutes. That is a terrible idea, it looks like the weight is hanging from the top teeth. I wonder if it would damage your teeth by pulling them out, your gums are malleable, mouth breathing is enough to push your teeth forward as is resting your tongue on your teeth according to my dentist. Everyone knows the best way to improve your jaw is to talk alot of ****, worked well for muhammad ali.
Amazing, no longer will I have to kill spiders with pencils that stab me in the hand, sir, I would like 500 units of your spider killer device
Well althouhg this is funny as hell i saw canelo doing similar thing with a towel and a ktettlebell i think.
Only in America. You cannot find these advanced devices back in Russia where people are still killing spiders with there hands and napkins like cave men
Thanks for the comments..I've sold many Rock Jaws and so far no one has complained about it taking their teeth out of their mouth...I use the product every day and have had no teeth issues. The Rock bag is only 3 lbs . It's not a bowling ball. My jaw and neck is like a rock.
How's the sales of your **** jaw device doing, somehow I think your insipiration for your device must have come from watching gay porn, you needed a device to strengthen your jaw for all the dicks you plan to suck
Guys you need to think about your rude comments. In 1974 a man named Gary Dahl sat at a bar with his friends and told them he was going to invent a Pet Rock..his friends laughed at him and his idea and told him what a stupid idea that is. Mr. Dahl went through with his idea and in 6 months time he sold over 5 million Pet Rocks. He banked over 15million bucks and closed his business. Rock Jaw is a new product and it works very well. .yes people buy it. Don't hate...congratulate.
