ok now i've been deadlifting the past 5 months and just a few weeks ago i was deadlifting and i felt my lower back and i could tell that the left side was bigger then my right. My back feels fine when i'm deadlifting, but Like a dum noob my girp was left hand under grip and right hand over grip for the frist 2 months, then the past3 months just did both over hand grips. Now could this be why my back is uneven or doesn't it matter with the style of grip i use? Could it also be my genetics?
