Cardio Questions:
Cardio is short for cardiovascular exercise, or in other words exercise which raises your heart rate. Now for some of us, beginners especially, almost any form of exercise will raise your heart rate to some extent. However in general when we think of cardio exercises, they are the types of exercise that are continuous in nature and use large muscle groups (most commonly the legs) often with little or no applied additional resistance. Examples would be walking, running, cycling, swimming and so on.
