I would recommend the wellness information and programs provided by the cardiovascular network at Meridian Health in NJ. They provide you complete information in relation to your diet, nutrition, exercises and lifestyle changes that need to be made for strengthening your cardio fitness. Consult them and alternatively look at their website for more information.

So, this extra amount of blood increases the oxygen that can be delivered to your body's working muscles. Aerobic exercise includes swimming, running, cycling, walking and boxing.
