I've completed week one now and I can feel the difference mainly in my breathing between run cycles.
However at the end of every run I get a pain in the muscles at the bottom of my back on right hand side at the hip
Am I doing something wrong? Might sound like a rookie question I don't know but any advice is welcome!
(I will mention that I'm doing this by doctor's orders and am currently running in Nike air force one's. haven't had a chance to get proper running trainers till next week)
