After a year of squatting, my hips have gotten really tight and sometimes it cracks. It's real uncomfortable at times and I'm not at all flexible in my range of motion these days, and I'm not sure if this is a result of that. I thought squatting was supposed to strengthen my hips? What went wrong? I've emphasized on correct form and everything I don't think I've been doing them incorrectly I've been doing these stretches too but to no avail.
