I usually do cardio 3 to 4 times out of 5 of my lifting sessions during the week. The cardio is usually running on the treadmill for about 15 minutes at a fast pace. I just started drinking 1 serving of grape juice after my whole workout to get the simple carbs in my body. My question is should I drink the grape juice immediately following my workout, before the cardio, or should I continue to drink the grape juice immediately following the cardio, after the whole workout? Does it make a difference?
