Why You Need Cardio Exercise..It's not just for weight loss anymore

By Paige Waehner.

Each week I get questions about cardio--how often we should do it, how hard we should work and why we need it in the first place. Many of us are confused about what to do because there are conflicting opinions about how much cardio we really need. The ACSM recommends 3-5 days of cardio for about 30-60 minutes. Bill Phillips, creator of Body for Life, recommends 20 minutes of high intensity cardio 3 times a week. Jorge Cruise, author of '8 Minutes in the Morning' says we don't even need cardio exercise. My recommendation? Forget the rules and get back to basics: Cardio isn't just for weight loss.

Our Bodies Are Made to Move

If you have a sedentary job, think about how your body feels at end of the day. Do you have tight muscles, an aching back, feel exhausted even though you haven't done anything physical? Maybe your shoulders burn from tension and your head hurts from staring at a computer screen for too long. Now, think about how your body feels after a workout. Your muscles are warm and flexible, the blood is pumping through your body, providing oxygen and energy. You feel energized, confident, proud of yourself and ready to take on the world. It's much different, isn't it? Our bodies are made to move--not sit around all day and yet, that's exactly what we're doing.

Next, take a moment to remember all the benefits of cardio exercise:
    * Weight loss
    * Stronger heart and lungs
    * Increased bone density
    * Reduced stress
    * Reduced risk of heart disease and some types of cancer
    * Temporary relief from depression and anxiety
    * More confidence about how you feel and how you look
    * Better sleep
    * More energy
    * Setting a good example for your kids to stay active as they get older

Notice that weight loss, while a big focus for many people, is only one benefit of cardio. Despite that, weight loss is often our only goal and not just for health, but to look good. While there's nothing wrong with wanting to look good, having that as our only goal can make exercise harder. Why? Because losing weight takes time...what happens if you don't see results on your timetable? Where will your motivation go if the scale doesn't cooperate? Open your mind to other reasons to exercise--you might just find new ways to make exercising easier.

If you look at the benefits listed above, all of them translate into feeling good now and in the future….Have we forgotten that being active can make our lives better? Moving around increases blood flow to our muscles, strengthens the heart and lungs and teaches the heart to work more efficiently. Not only that, when you exercise you set a good example for your kids to do the same, which could mean a better future for them.
