When I deadlift, I can lift the weight easily, my lower back arched good, but my upper back starts round. Is this a bad thing?
For example: I know this is nothing, but I'm deadlifting 155 kg for 3 reps and my thoracic vertebrae round lifting this weight. To keep a perfect arch I would have to drop the weight to 120-130kg.
Should I drop the weight until I can keep a perfect arch in my spine?
Should I implement both styles? ie: Most of the time with low weight and perfect form with a few heavy sets (thoracic rounding) every couple weeks?
Should I quit my bitching and just continue to lift as much as I can?
