Hi, I'm new to this, not fit and never really have been, apart from a brief spell 20 years ago when I did a 10K very slowly and then stupidly gave it up. I'm also a couple of stone overweight. I did my first run yesterday and was really struggling to breathe after the 6th one minute run. I tried this couple of years ago but gave up very quickly as I wasn't progressing at the same speed as the programme; in week 2 I couldn't move on to 90 secs run. Did anybody else find this? Should I repeat week 1 again?
