Back strain or back WORK?
Ok I don't understand backs. People say don't put strain on them, you'll wear them out. But isn't putting strain on something kind of how you work it? I'm young and I definitly have a weaker back then I should at my age. So far I've been doing a lower back thing where you lay on your forearms and toes for awhile. I also lay on my stomach and lift my right arm and left leg, then alternate. I do pullups, not sure how wide I should have them be though.
I USED to lay on a flat bench with the barbell below the bench on the floor, then raise it until it touched the bottom of the bench. But this would make my back hurt like hell the rest of the day, so I stopped, was that a good idea?
I need to do some deadlifts, but I read if they aren't done exactly right they will screw you over.
So what's the difference between strain and a workout? And what else can I do for my back?
