Sam’s and Mary’s programs represent only two of a variety of exercise choices and progressions. Whether the choice is walking, pushing, cycling with upper or lower body, swimming, dancing or elliptical machine, the benefits of a more efficient cardiorespiratory system are achievable, and the numbers are all good – as long as they make sense for your individual needs and goals. Getting a little out of breath can be a good thing, as long as it is part of a smart and appropriate plan, and always remember that most important for older adults is safe and appropriate progression. Begin slowly and gradually increasing your time and intensity. This may take weeks or months. Check with your doctor before beginning an exercise program so that he/she can alert you to any modifications that may apply to your individual health history. Also, be certain to include a 5-to-10-minute warm up and cool down.
