i've been bulling conventional ever since i started, and noticed that my right spinus erectus gets worked harder. i think i'm paranoid or something cause i swear i can see a difference in my left vs right spinus erectus in the mirror, but can't tell cause i have to turn my back when looking at my own back in the mirror. it almost feels like i have scolliosis or something then this week, i tried pulling sumo, and i felt that my both sides of my spinus erectus were worked equally. does this suggest anything? if my conventinoal pull is working one side harder than the other, what could be wrong with my form?
