Lower Back Pain/Tail bone
So I've been biking 8 miles mon-thurs to class these past like 5 weeks, and I'm focusing on explosive speed as a sprinter. I stopped conditioning early this summer and worked on power, blocks and all that jazz. I occassionally did a distance run or two. around 2-5 miles.
I ran today for the first distance run in awhile and my lower back started to hurt and tighten up, I never had this happen to me before. Then it got to the point where I couldn't run anymore and I only went half a mile. It felt tense and a squeezing sensation. After running I'm fine, it happens only when I do. Any ideas on what it is?
my workouts have been:
Monday - short sprints
Tuesday - Plyometrics
Wednesday - Rest
Thursday - High weight low rep (deadlifts, cleans, bench etc)
Friday - Short sprints
