This is Odd, But I'd Like to Know
I've noticed that if I apply pressure to lower back I don't feel it all that much. I use my lower back for everything (deadlift, squat, etc); I never isolate any muscles. I have a strong an stable core at my size. If I pinch the skin of my lower back i feel it. I was wondering.
If you apply pressure to your lower back (erectors) if you feel it? I've also realized that if I am showering with hot water, I don't feel it that much there either, as if the thickness of my lower back masculature somewhat protects the nerves from these feelings.
