You breath in and the oxygen enters your lungs. It slides past some membranes and dissolves into your blood, binding quickly to the red blood cells. Within moments your heart beats and your oxygenated blood races off through ever narrowing arteries untill it squeezes into the capillaries that permeate every muscle in your body. Then "pop" the oxygen unbinds from the red blood cells, re-dissolves and diffuses its way over to your eager muscles.
How do you improve the process? How do you get more oxygen to where you need it when you exercise? The answer is simple: do Cardio Training! When you train cardio you positively influence almost every step in the process of bringing oxygen to your muscles.
One of the best ways to get a cardio workout is to go cross-country skiing. Experts agree that cross-country skiing is among the most aerobically complete activities due to the high level of involvement and intensity of use of the upper and lower body muscles.
