But in reality, any form of exercise is cardio exercise: long, slow distance is cardio; weight training is cardio; boot camps are cardio. Cardio is anything that raises your heart rate and makes you breathe heavy.

Cardio’and not just the traditional type of long, slow distance cardio helps you:
– burn calories,
– improve metabolism and
– strengthen your heart and lungs.

With so many exercise choices, how do you know when you’re doing cardio?

It’s simple: Your heart rate goes up and you breathe heavier. You must engage the major muscle groups ‘for example, your arms or legs or both. When you involve the large muscles in the body, they need more oxygen, which increases your respiration and heart rate.

How often do you have to do cardio to get the most out of it?
