I've just gotten into mountain biking, and have only been riding for about a month now. Between the weather and a broken fork, I've only logged about 7 or 8 hours so far.
After every ride I go on, my upper back/lower neck hurts pretty bad. The pain is in my muscles right near my shoulder blades. I know that it is caused by being hunched over with my head up. I'm not sure if it is a result of bad posture, or just because I'm using muscles that I'm not used to using. Can anyone offer any advice here? Will these pains go away after I strengthen my muscles a bit, or should do I need to adjust my posture? I've tried several positions for my seat, but haven't had any luck yet. Any ideas?
