My last "run" or should I say "shuffle" of Week 2 is on Thursday and I am due to start Week 3 on Sunday and I am dreading it. Considering I am over 50 and overweight and I haven't exercised for years (apart from walking) I have been surprised how well I have done so far with no aches and pains. However, I do find the breathing hard and I find it impossible to concentrate on breathing properly and getting my legs moving at the same time! I can just about manage the 90 seconds of slow jogging but I think I am going to really struggle with 3 minutes. How has everyone else coped with Week 3? Any helpful tips will be gratefully accepted.
