I know I've been asking alot of questions lately and posting alot, but I've finally started back strong and I'm encountering some things I haven't before. So I'll try to keep the volume down.
Last time I deadlifted I used perfect form with my back arched slightly upward, and my lower back went bananas. I couldn't bend over without extreme soreness for 1/2 an hour after lifting. My lower back felt as if I had a stiff neck. Is this a problem? I had no pain afterwards or today. It felt almost as if my lower back muscles were extremely pumped up.
