Exercising reduces the risk of heart disease by making the heart muscle stronger
and thicker, allowing it to pump blood with fewer beats. Exercise lowers the
unhealthy cholesterol in your blood, thus reducing the risk of a heart attack.
It also burns calories, allowing it to aid in weight loss as well.
There are two different types of exercise: aerobic and anaerobic.
Aerobic
Exercise
Aerobic
exercise is defined as being long in duration and low in intensity. You use
the same large muscle group for 15-30 minutes (or longer) and maintain 60%-80%
of your maximum heart rate.
Biking, walking, jogging, cross-country skiing, and swimming are some common
aerobic exercises. Aerobic activity increases the efficiency of your heart and
lungs by escalating the oxygen intake and enabling the heart to use it more
adequately.
Anaerobic
Exercise
Contrary
to aerobic exercise, anaerobic exercise is short in duration yet high in intensity.
Anaerobic exercise emphasizes building muscle, as opposed to burning oxygen.
Weightlifting, sit-ups, push-ups, sprinting, racquetball, soccer, football,
and downhill skiing are some examples of anaerobic exercise.
It is important to exercise at least three times a week. Usually, the most effective
types of exercises are those that combine aspects from both aerobic and anaerobic
exercises. If you have medical problems or are over 40, ask a doctor what is
right for you.
