There are three kinds of fitness:

  • Aerobic fitness.
    Aerobic activities condition your heart and lungs. Aerobic means "with
    oxygen." The purpose of aerobic conditioning is to increase the amount
    of oxygen that is delivered to your muscles, which allows them to work
    longer. Any activity that raises your heart rate and keeps it up for an
    extended period of time will improve your aerobic conditioning.
  • Muscle strengthening.
    Stronger muscles can mean either more powerful muscles that can do
    bigger jobs (such as lifting heavier weights) or muscles that will work
    longer before becoming exhausted (endurance). Weight training
    (resistance training) or simple exercises such as push-ups are two
    examples of ways to focus on muscle strengthening.
  • Flexibility.
    Like aerobic fitness and muscle strengthening, flexibility is a result
    of physical activity. Flexibility comes from stretching. Your muscles
    are repeatedly shortened when they are used, especially when
    exercising. They need to be slowly and regularly stretched to
    counteract the repeated shortening that happens through other
    activities.
Understanding the differences between each kind
of fitness will help you set your fitness goals. Reaching a balance
between the three is important because they affect each other, and each
contributes to total fitness. Some physical activities involve
more than one kind of fitness. Some activities that are thought of as
aerobic exercise, for example, also strengthen muscles (swimming,
cycling, skiing).
