Perhaps it also depends on each individual's
body (and its comfort zone) as well.
For my one office buddy, he wakes up, instantly springs out of bed (almost doing back flips across the room) and does a 1 hour
cardio session before eating
breakfast. He's a morning person and for him, the earlier he wakes up, the better. re: Any time after 5:00 AM is sleeping in. After exercising, he has a small
breakfast and a larger size AM snack. Thus, even distribution of morning
calories / carbs - after his
body exercises.
For me, I'm NOT a morning person. Never was and probably never will be. The later I can sleep in, the better. 9:00 AM is my normal winter season wake-up time. For my
body, it feels best to exercise AFTER
breakfast. re: Between 10:00 - 11:00ish window. If I exercise before
breakfast (or before 9:00 AM), my
body feels "over drained" the rest of the day. Thus, I don't have remaining
energy for my normal noon time and dinner time exercise sessions. Over drained because I exercised too early in the morning.
As a suggestion, perform one's morning exercise time (before or after
breakfast) for your unique
body's "comfort feeling". If it likes exercising after smaller size
breakfast, go for it. If it likes exercisting before
breakfast meal, do it instead. If something is "comfortable" on your
body, one will continue to perform that exercise daily routine for longer period for much longer calender time.
Hope this helps as well...
