Progression
As your become fitter, a higher intensity of exercise is required to create an overload and therefore provide
continued improvement
Overload
This is where you exercise at a level above that which can be carried out comfortably. The intensity, duration
and frequency of exercise should be above the training threshold and should be gradually increased as the
body adapts to the increasing demands. As your fitness level improves, so the training threshold should be
raised.
Working through your program and gradually increasing the overload factor is important.
Specificity
Different forms of exercise produce different results. The type of exercise that is carried out is specific both
to the muscle groups being used and to the energy source involved.
There is little transfer of the effects of exercise, i.e. from strength training to cardiovascular fitness. That is
why it is important to have an exercise program tailored to your specific needs.
Reversibility
If you stop exercising or do not do your program often enough, you will lose the benefits you have gained.
Regular workouts are the key to success.
WARM UP
Every exercise program should start with a warm up where the body is prepared for the effort to come. It
should be gentle and preferably use the muscles to be involved later.
Stretching should be included in both your warm up and cool down, and should be performed after 3-5
minutes of low intensity aerobic activity or callisthenic type exercise.
Warm Down or Cool Down
This involves a gradual decrease in the intensity of the exercise session. Following exercise, a large supply of
blood remains in the working muscles. If it is not returned promptly o the central circulation, pooling of
blood may occur in the muscles
Heart Rate
As you exercise, so the rate at which your heart beat also increases. This is often used as a measure of the
required intensity of exercise. You need to exercise hard enough to condition your circulatory system, and
increase your pulse rate, but not enough to strain your heart.
Your initial level of fitness is important in developing an exercise program for you. If you are starting off, you
can get a good training effect with a heart rate of 110-120 beats per minute (BPM). If you are fitter, you will
need a higher threshold of stimulation.
To begin with, you should exercise at a level that elevates your heart rate to about 65 to 70% of your
maximum. If you find this is too easy, you may want to increase it, but it is better to lean on the conservative
side.
As a rule of thumb, the maximum heart rate is 220 minus your age. As you increase in age, so your heart,
like other muscles, loses some of its efficiency. Some of its natural loss is won back as fitness improves.
