A while ago I was going curls with the z bar with enough weight that it was pretty difficult to do. I may have dropped/slammed the bar onto the preacher rack and that hurt my forearm a little bit. This was about a month ago or more.
Yesterday I was doing curls with dumbells with much lesser weight and when I put it down and released it, i could feel the pain in the forearm again. I’ve taking it slow, if do hammer curls instead which don’t hurt.
