is there a training to make your jaw strong?

probably his moms side?

 

Take roids and chew five pieces of gum after all your jaw have muscles.Boom Boom should do that.

 

get into puhup positon put your jaw on the floor and open your mouth so that you pushs yourself up with your mouth.

 

yes, have you tried Rock Jaw Neck and Jaw Strengthener?

 

If you're in any contact sport and you're not regularly strengthening your neck you're an idiot. Neck girth prevents concussions, and stiffer neck muscles prevent concussion.

 

If you're going to attempt to make sales, you may want to check the posted date before you post. I doubt this person is still looking for an answer in this thread 8 years on.
