I am doing cardio on an empty stomach 2 times a week for 20 minutes, sometimes on rest days, sometimes on workout days. I workout 4 times a week. I am doing cardio to minimilize the fat gain (from the needed food to gain muscle's). But my question is if this is good. Because my maintenance is 3000 kcal and I eat 3300 kcal, but if I do cardio I just use the needed kcal to gain muscle. (My goal is to gain muscle's)
Hope I explaned it right.
