What Is Cardio?

Everyone says they do cardio, or is told to do cardio, so what is it? What most people do isn't cardio at all. It's distance training. They jog or run or do an elliptical, trying to go for as long and as far as they can. Trying to go longer or farther each time.

That's really a distance exercise, which does use cardio of course but true cardiovascular and cardiorespiratory exercises should increase your Vo2 max, decrease your recovery time, increase your muscle endurance threshold, increase the amount of oxygen in your blood, lactic acid treshold, etc.

To best do this, you need to do things short and intense. One is mindless, one has a goal. Never train mindlessly.
