Answer: whenever you can
I'm a believer in getting what you can throughout the day - i.e. I park in far corners in parking lots, get off the bus 3 stops earlier (or later), never take the elevator or escalators in malls/buildings, own a 2400 sq ft, 3-storey house that clean myself (11 steps to each floor), and live within a click of everything I need and "walk to shop" every other day (milk bags & cans are heavy
Exercise is great to do after a meal as it improves the whole metabolism/digestion of food and insulin thing and there's less potential for lows (especially for Type 1's). If you're into the really into the aggressive exercise, morning through to supper is the best time for most. The more casual exercise can be done at any time without as much impact to BGLs. Exercising within a few hours of bedtime is not recommended.
Keep in mind that exercise can affect BGLs for hours afterwards.
