So I have noticed that after lifting for some time my lower back has develeoped sort of a natural arch when I stand. Is this proper posture? You hear about people saying your back should be straight and all that but mine isn’t.
My upper body posture is fine but like I said my lower back has a natural arch in it. Is this just from frequently having a slight arch for doing lifts (squat, bench press, deadlift, etc)? Or is there something out of whack?
