What is Nitric Oxide and what does it do?
Getting enough blood to the muscles when you are working out can be the difference between a good workout and a great one. Whenever you pump some iron, your body switches its pump on as well, pushing the blood through your body at a faster rate. While you are performing, your endothelial cells, which line all of the arteries in your circulatory system, release more of a substance called nitric oxide (NO2).
