I'm 7 weeks into Bill Starr's 5x5 and I can't complain. I haven't plateaued yet and my numbers keep climbing. However, I'm having some tightness/pain in my left hip on the front side. It has always popped, but as of late, it's irritated. Nothing excruciating, just a nuisance. I have a busy week traveling, so I decided to take a week. Is this a fatal mistake so early in this program?
