I'm trying to prepare for a 5K. I'm in great physical shape with the exception of my lower back. Right after the first mile my lower back really tightens up. If my lower back doesn't tighten up, I'm in a great situation in terms of performance..
What do you think are the causes of this? What can I do to prevent this?
I've had this problem in high school and gave up cross country and tried to slowly build up but no matter what it tightens up
