When I do a heavy set of deadlifts (130kg x 5) my upper back rounds quite a bit as you can see. Is this a problem and should I decrease the weight and try and fix it? I’m sure it could also be due to my “round shouldered” posture. Some people seem to say upper back rounding is fine as long as the lower back is straight and others say it isn’t.
