I've been getting headaches during deadlifts and bench presses. I know I don't have too much weight. On the deadlift I'm not 100% I have the technique right, but on the benchpress I do. I bring the weight to my chest then bring it back up. I don't have headaches during any other exercise, however the benchpress and the deadlift are the two exercises that are the toughest. I was wondering if I wasn't breathing enough(it's not like I hold my breath or anything though) and if anyone had any breathing tips or techniques.
