>>8167That won't do shit
If you want to jawmaxx you need to buy some gum preferably the tough foreign stuff and chew it for a hour a day for as many days as you can handle. By the time you're done you your jaws should feel weird and on the edge of TMJ.
Then once that becomes too easy buy some jaw exercisers on the internet, get the ones that go on each side of your mouth because I bought the one that you use in just the front and they started to make my teeth spread apart.
Also the lower the bodyfat the better so unless you were blessed with Chadjaw genes like the Otamin you're going to want to sit at 12% and lower.
