I think I'm pushing off with my left leg more than my right leg, I can't think of another reason. My left leg is much more sore, my right leg I don't really feel anything besides anything minor. My left leg feels completely different, I can only feel it when I start walking. I just started running/excercising last week. Don't know if it's since I just started, but my right leg should feel the same. Is this common or is it since I have bad form?
