The Basics
Exercise is a particular form of physical activity — planned,
purposeful physical activity executed with the intent of gaining fitness
or other health advantages. Exercising at a health club, swimming,
cycling, running, and sports, like golf and tennis, are all kinds of
exercise.
How can you tell if an action is considered moderate or vigorous in
intensity level? If you are able to talk although executing it, it's
moderate. If you have to stop to catch your breath after saying simply
a couple of words, it's vigorous.
Depending upon your fitness level, a game of doubles tennis would
likely be moderate in intensity level, although a singles game could be
more vigorous. Also, ballroom dance would be moderate, however
aerobic dance could be considered vigorous. Once again, it's not
simply your choice of activity, its how much effort it demands.
Ideally, an exercise regimen should include elements designed to
better each of these components:
Cardio-respiratory endurance. Better your respiratory endurance —
your ability to engage in aerobics — through actions like brisk
walking, jogging, running, cycling, swimming, jumping rope, rowing,
or cross-country skiing. As you reach distance or intensity level goals,
reset them higher or shift to a different action to keep challenging
yourself.
