What is considered excercise?

Answer 1

Cardio is merely a short way to say cardiovascular training or aerobic exercise. The key is in the heart rate. During cardio exercises, you want to increase your heart rate to around 60 to 80 percent of the maximum rate for your age. Any exercise that gets you moving can accomplish this task. A brisk walk, jogging, riding a bike or dancing are all examples of cardio workouts.
