[QUOTE="ElyDave, post: 606933, member: 74042"] First of all, intensity is relative, and not measured by speed but by heart rate and relative effort. At my last race I was two hours behind the winner, others were 3 or 4 hourse behind me, all worked just as hard. That's why I'm a firm believer in heart rate monitors to manage training intensity. As for before/after, depends what you are trying to achieve? If it's fat burning/weight loss, there is plenty of evidence that fasted (before breakfast) training is more effective as your body is prepared to go into fat burning earlier with a lower level of circulating glucose, but you need to do it at lower intensity to avoid that liver dump. If you are trying to lower a high BG (especially if on insulin) or train for speed, post meal exercise is probabaly better. Looking bigger picture though, what exercise will do is increase insulin sensitivity and if you keep that up regularly 2 days out of three or similar, then you'll maintain that insulin sensitivity which may help you with both dose and BG management.
