/sp/ - Sports & Exercise

here is the thing that I am using. not this, i use bigger one now. but it does replace jawliner!
this thing here is basically a hook, i just put towel and concetrate jaw lifting. like my heckin' jack hanma o algo.
but i wonder if my jaw will be assymetrical as result of the training, i had so much fcking trouble with pinpointing how to put towels over the jaw
I also wonder if i should… nah probably not. frontal teeth might increase chance of injury though.
assymetrical muscle growth could be real problem, but hopefully it will balance itself out each day.
