Morning cardio

i use to train at this shaolin school…we would sleep over at the school..wake up at 530-6 in the morning
do some light stretches/warm up the body
than we jog/run for a good 1-2 miles
more stretching…basic kicking/punching drills
forms and lots of forms
finish it off with more strength training stuff/sprints/push up/ etc!
for a good 2-3 hrs in the morning!!!

man i was in the best shape of my life!!! and i felt good for the rest of the day also and had no problems!!!

also…shaolin monks/china wushu atheletes all train hardcore early in the morning…and train a good 8 hrs a day…they look fine to me in the long run too also, look at jet li..he stil look healthy to me…so i dont think its bad thing

I think it depends on the intesity as was stated earlier.
If you’re training below 70% or 65% of your VO2 max, and it’s a pretty consistant pace (running), you could (and probably should) do it in the morning before eating.
For a very intense workout (like my boxing or circuit training) that is sporadic and frequently in the 75-90% vo2 max area, you really need some calories to carry you through it. I don’t bother people with going into crazy details of measurements and types of calories, but something along the lines of a light to medium sized snack 20-40 min before you do the routine. Suppose you could eat one of the plethora of “exercise bars” types, but I’m not a fan of those.
