Cardio is needed for all of us. Most health & wellness studies out there will rarely tell you, the reader, to "never do cardio". In a time of our lives where 1/3 of the world population are considered overweight or obese (many statistics makes it as high as 68% overweight/obese here in the states), cardiovascular conditioning is highly recommended to all in order to achieve maximum quality of life.
The U.S. Department of Health and Human Services and the American College of Sports Medicine (ACSM) recommends that adults between the ages of 18-64 should engage at a minimum of 150 minutes (about 2 1/2 hours) of moderate-intensity aerobic activity spread over the week. By doing so, Americans may decrease risk of chronic diseases such as diabetes, high blood pressure, heart disease and osteoporosis.
These recommendations can easily be achieved by doing one or a mixture of the following:
* Powerwalking 1-2 miles daily
* attend a couple cycle/spinning classes a week
* attend a couple step aerobic classes a week
* perform light-to-moderate, high repetition, resistance training a few times a week
Incorporating these activities will in the long run improve functions of the heart, lungs, vessels, and the musculoskeletal system.
