I am listening to my body and am holding back on doing Week 9. For the last two weeks i have had achey knees that have not really gone away. I have got some running shoes but when I bought them for the gym 2 years ago didn't know gait analysis existed. I think I am going to go to Bath on Sat and get it done in the running shop. Am I right????? It seems a shame but I cant damage my knees, Ive still got a lot of dancing to do. I can always repeat week 8 right??
