��The pump had been renowned since the birth of bodybuilding, but what causes the pump?
-
��When you lift weight, you cause damage to muscle cells. This causes an influx of sodium and water into the cell, while an efflux of potassium outside of the cell. In addition, fluid leaving the muscle is restricted, but the fluid going to the muscle is not restricted. This means your muscles are filling with fluid, which is why they look full and hard when you have a great pump!
