Do a pretty long cardio run (30-45 min) in the mornings on OFF days to cut fat. Is this counterproductive? I've heard to do bulking and cutting in phases but I don't like the idea of that. Besides if I do it in phaes, I feel that when the cutting starts, the cardio will be weak in the beginning. If I want to maintain as much muscle as possible doing cardio, does it help to just take L-glutamine on only the cardio days?
