hit, but it's probably wrong and will probably fuck you up
you have to stiffen your neck and jaw, and kinda push with your diaphram. This is kinda weird. Keep doing it till it stops hurting. At that point you're probably doing it right. Keep in mind that your throat should always be moist. You'll notice at shows vocalists always take a drink at least between every song and often during instrumental sections as well.
next person will correct me
