You are welcome, not sure how useful it is, there are far more knowledgeable people on the daily excercise thread.
I walk almost every day, and the excercises are an attempt to excercise the rest of me. Re your second question, how does it help with with BG; if i dont excercise for a few days my fasting BG will sneek up to approx 6.4 , and my daily average also around 6.2( 2 hours post meal). So about 0.7 mmol/L decrease with the excercise. There is probably a longer term effect also, if you loose weight, gain some muscle....that sort of thing.
