Exercise

I've just completed the dafne course last week and am just trying to put everything I have learnt into practice. Can anyone give me advice regarding how exercise affects your levels. I understand the principle of giving less insulin but would like to know more about how it affects you the following day etc

In my early days when playing basketball at age 30 - 40 I had usual insulin and more carbos. It was the following day that I found I needed less insulin (Basketball was played at night) Now I'm 70 I find I need less insulin on the day of exercise (riding a bike, mowing lawns, gardening, washing car) plus extra carbos. I found the fitter I was the less insulin I needed but now days exercise seems to drop my sugars more immediately. But remember, we are all different and you need to work out your own requirements.
