I agree pumps can depend on the type of workout you do. Yet, the quality of pumps you get with appropriate supplements my be superior to that of pumps from workouts only. Finally, I do not quite agree that pumps do not mean a thing. Vasodilation/pumps create an excellent environment for superior transportation of nutrients into the blood stream and cellular tissue, triggering anabolic processes. The full anabolic process unfolds during rest, as we know. So, vasodilation/pumps are cool.
