Yet another cardio question thread

**Corpsman** · 03-31-2011, 11:09 AM

I have done some reading I think I understand that if I do cardio to lose belly fat, then I should stay in the "fat burn" zone according to my pulse rate. I think no more than 30 minutes is recommended. If I want to do cardio for staminia and endurance, then I go into the "cardio" zone and can do this longer BUT I have to preload with carbs. Although I am not sure how much carbs or when to preload with.

Is 30 minutes about right? For endurance/stamina how long should I go?

Intensity and duration have an inverse relationship. The more intense the workout the shorter in duration. Less intense the longer the workout should be.

Your body, under normal circumstances, is able to store glycogen. That store of glycogen should last you at least 90 mins for cardio and, in some cases in regard to diet, up to 120 mins. You really shouldn't need to preload carbs for a 30 min workout.
