I am starting to train on the heavy bag once again and after I throw a left hook to the body a few times my elbow starts to hurt like hell. The pain usally goes away after an hour or so, butI know it isn't supposed to be there in the first place.
Im 20 yrs old, 165lbs, and I am using 14oz everlast training gloves. The heavy bag is an 80lb everlast never tear. Also it seems that most of the "stuffing" has gone towards the middle and the bottom because the top of the bag doesnt seem to have very much in it anymore, but the bottom and middle seem to be harder than they used to be.
