When can I start exercising slowly? Just a few step things or an exercise DVD? I want to try and avoid flabby arms etc. I am also hoping to get fit enough to run 1 or 3 miles at the harefield fun run in september. the last 2 years I have walked the mile with the girls, but am hoping that Peter will be well this year to take the girls on the mile by himself, and for me to run it.
