EXERCISE INSTRUCTION

TRAINING GUIDELINES
Exercise is one of the most important factors in the overall health of an individual.
Listed among its benets are:
• Increased capacity for physical work (strength endurance)
• Increased cardiovascular (heart and arteries/veins) and respiratory eciency
• Decreased risk of coronary heart disease
• Changes in body metabolism, e.g. losing weight
• Delaying the physiological eects of age
• Reduction in stress, increase in self-condence, etc.
ere are several components of physical tness and each is dened below.
STRENGTH
e capacity of a muscle to exert a force against resistance. Strength contributes to power and speed.
MUSCULAR ENDURANCE
e capacity to exert a force repeatedly over a period of time, e.g. it is the muscular endurance of
your legs to carry you 10 km without stopping.
FLEXIBILITY
e range of motion of your joints. Improving exibility involves the stretching of muscles and
tendons to maintain or increase suppleness, and it provides increased resistance to muscle injury or
soreness.
CARDIO-RESPIRATORY ENDURANCE
e most essential component of physical tness. It is the ecient functioning of the heart and
lungs.
AEROBIC FITNESS
Is an exercise of relatively low intensity and long duration, which depends primarily on the aerobic
energy system. Aerobic means "with oxygen", and refers to the use of oxygen in the body's metabolic
or energy-generating process. Many types of exercise are aerobic, and by denition are performed at
moderate levels of intensity for extended periods of time.
ANAEROBIC TRAINING
Is an exercise intense enough to trigger anaerobic metabolism. is means “without oxygen” and
is the output of energy when the oxygen supply is insucient to meet the body’s long term energy
demands. (For example, a 100 meter sprint.)

8
OXYGEN UPTAKE
e eort that you can exert over a prolonged period of time is limited by your ability to deliver
oxygen to the working muscles. Regular vigorous exercise produces a training eect that can increase
your aerobic capacity by as much as 20 to 30%. An increased VO2 Max indicates an increased ability
of the heart to pump blood, of the lungs to ventilate oxygen, and of the muscles to take up oxygen.
THE TRAINING THRESHOLD
is is the minimum level of exercise which is required to produce signicant improvements in any
physical tness parameter.
OVERLOAD
is is where you exercise above your comfort level. e 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 tness level improves, the training threshold should rise. Working
through your program and gradually increasing the overload factor is important.
PROGRESSION
As you become more t, a higher intensity of exercise is required to create an overload and therefore
provide continued improvement.
SPECIFICS
Dierent forms of exercise produce dierent results. e type of exercise that is carried out is specic
to the muscle groups being used and to the energy source involved. ere is little transfer of the
eects of exercise, i.e. from strength training to cardiovascular tness. at is why it is important to
have an exercise program tailored to your specic needs.
REVERSIBILITY
If you stop exercising or do not do your program often enough, you will lose the benets 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 eort to
come. It should be gentle and preferably use the muscles group 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 calisthenic type exercise.
WARM DOWN OR COOL DOWN
is 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 to the central
circulation, pooling of blood may occur in the muscles.

9
HEART RATE
As you exercise, your heart beat increases. is is often used as a measure of the required intensity of
an 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 tness is important when developing an exercise program for you. When starting,
you can get a good training eect with a heart rate of 110-120 beats per minute (BPM). If you are
more t, 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 nd 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, your
heart, like other muscles, loses some of its eciency. Some of its natural loss is won back as tness
improves. e following table is a guide to those who are “starting tness.”
Age Target Heart Rate 25 30 35 40 45 50 55 60 65
10 Second Count 23 22 22 21 20 19 19 18 18
Beats per Minute 138 132 132 126 120 114 114 108 108
PULSE COUNT
e pulse count (on your wrist or carotid artery in the neck, taken with two index ngers) is done
for ten seconds, taken a few seconds after you stop exercising. is is for two reasons: (a) 10 seconds
is long enough for accuracy, (b) the pulse count is to approximate your BPM rate at the time you are
exercising. Since heart rate slows as you recover, a longer count isn’t as accurate.
e target is not a magic number, but a general guide. If you’re above average with your tness, you
may work comfortably a little above that suggested for your age group. e following table is a guide.
Age Target Heart Rate 25 30 35 40 45 50 55 60 65
10 Second Count 26 26 25 24 23 22 22 21 20
Beats per Minute 156 156 150 144 138 132 132 126 120
Don’t push yourself too hard to reach the gures on this table. It can be very uncomfortable if you
over exercise. Let it happen naturally as you work through your program. Remember, the target is a
guide, not a rule, a little above or below is just ne.
Two nal comments: (1) don’t be concerned with day to day variations in your pulse rate, being
under pressure or not enough sleep can aect it; (2) your pulse rate is a guide, don’t become a slave
to it.

10
MUSCLE SORENESS
For the rst week or so, muscle soreness may be the only indication you have that you are on an
exercise program. is, of course, does depend on your overall tness level. A conrmation that you
are on the correct program is a very slight soreness in most major muscle groups. is is quite normal
and will disappear in a matter of days.
If you experience major discomfort, you may be on a program that is too advanced, or you have
increased your program too rapidly.
If you experience PAIN during or after exercise, your body is telling you something. Stop exercising
and consult your doctor.
WHAT TO WEAR
Wear clothing that will not restrict your movement in any way while exercising. Clothes should be
light enough to allow the body to cool. Excessive clothing that causes you to perspire more than you
normally would gives you no advantage. e extra weight you lose is body uid and will be replaced
with the next glass of water you drink. Always wear a pair athletic shoes.
BREATHING DURING EXERCISE
Do not hold your breath while exercising. Breathe normally as much as possible. Remember,
breathing involves the intake and distribution of oxygen, which feeds the working muscles.
REST PERIODS
Once you start your exercise program, you should continue through to the end. Do not break o
halfway through and then restart at the same place later on without going through the warm-up stage
again. e rest period required between exercises may vary from person to person.
