It builds the most important muscles in your body - your heart and lungs.

I find that when my cardiovasular system is in shape... I can go longer and harder in the gym, especially leg workouts. Less time between sets, etc.

"I can go longer and harder in the gym, especially leg workout" Yep, me too.

Also, you'll recover faster from a workout which means you'll be building muscle at a faster rate.

I believe the REAL importance is the positive benifits on for the Heart.

When it comes to fat-loss I personally feel that weight-training is more effective, although cardo is very good for cardiovasular health, and all around fitness.
