Stretch! Did you remember to do that before you started lifting, and briefly after you were done? I think it also helps to stretch right before bed after lifting, but I haven't done much in the way of control experiments.

I love the muscle soreness the next day or two after a hard workout. I don't even really think of it as soreness so much as tightness. That's the feeling of muscles growing!
