Nursing iffy knee over last two runs (w6r1 last Wednesday) and it was a knowlegeable person on here who recommended the knee exercises on the nhs website which I have been doing since. They are superb and I think when I dare to try w6r2 ( possibly tomorrow-fingers and toes crossed!!) I will in corporate them just before the warm up run.
I know a few others have/or are having similar issues. I really had no concern about my knees at the beginning and would recommend that newbies may be add a few as well. I wish I had in those earlier weeks to boost my strength a little more.
