I always exercise near the end of my fast.

Normally, I exercise at the end of my fast. Occasionally, I eat first, then wait an hour, then exercise.

My exercise routine is 2.75 miles on the treadmill which takes 51 to 52 minutes. I wear a heart rate monitor and set the incline to maintain 115 to 120 BPM. At my age, that equates to 75-80% of max, well into cardio...definitely burning glycogen. I have been doing this for several months and have no adverse side effects.
