I know it's been answered here before but anyway; when stretching how much force is enough or not enough? Yes I know, go to where you're not hurting yourself but can you hurt yourself without actually hurting yourself? I've heard of the dreaded "lig pop" not real sure I want to experience that but is that what I need to be pulling for or just before that "pop" I think I experienced a "head pop" the other day. It felt like my glands separated from the shaft for just a split second. It didn't really hurt just felt weird and scared the shit out of me. I can pull pretty hard most of the time and feel tender around the base and ligs when my session is over which I can handle but in the back of my mind I'm also worried about the dreaded toughening of the ligs where I won't be able to gain. Then I read about DLD putting his "foot down" so to speak on another exercise. Anyway just kinda of wondering how much force to use to be safe but also go after a good stretch.
