CONDITIONING GUIDELINES
The following guidelines will help you to plan your exercise program and exercise safely. Remember that
proper nutrition and adequate rest are essential for successful results.
WARNING: Before beginning this or any other exercise program consult your doctor. This
is especially important for pregnant women and new mothers, all people over
the age of 35, and those with medical problems such as heart disease, high or
low blood pressure, injuries, joint problems, obesity and asthma.

WHY EXERCISE?
Exercise has been proven essential for good health and general wellbeing. Regular exercise will:
Relieve tension and stress
Provide enjoyment and fun
Stimulate the mind
Help maintain stable weight
Control appetite
Boost self-image
Improve muscle tone and strength
Improve flexibility
Lower blood pressure
Relieve insomnia
TARGET HEART RATE
To train effectively you should aim to work in the heart rate zone appropriate to your age as stipulated
below. Please note this is a guide and your heart rate at rest and during training is determined by your
fitness level and other lifestyle factors as well as your age. If you reach the recommended beats per
minute below and feel you’re over-exerting yourself stop, rest and when you feel recovered return to
exercise at a lower intensity.

BEGINNERS GUIDE TO EXERCISE
If you’re beginning an exercise program for the first time or starting a new exercise program, you
must check with your doctor that you are fit to do so particularly if:
You have been diagnosed with heart problems, high blood pressure or other medical conditions.
You have not exercised for over a year.
If you are over 35 and do not currently exercise,
You are pregnant or are a new mother
You have diabetes
You have chest pain, or experience dizziness or fainting spells.
You are recovering from an injury or illness
WORK-OUT TIPS
Always perform a warm-up and stretching exercises before your work-out and a cool down and
stretching exercises at the end
Start slowly and build up your time, speed and resistance gradually; doing too much too soon can
lead to injuries.
If you are sore or tired, give yourself a few extra days to recover.
HOW TO BEGIN
Start with two or three 15-minute sessions per week with a rest day between work-outs.
Warm-up for 5 to 10 minutes with gentle movements incorporating the whole body such as walking
while swinging your arms in a circle and then stretch the muscles you’ll use during your work-out.
Seated cycling works mainly the quadriceps (thighs) and hamstrings.
Increase the pace and resistance to slightly harder than comfortable and exercise for as long as you
can. You may only be able to exercise for a few minutes at a time, but that will change quickly when
you exercise regularly.
End each work –out with a 5-minute cool down with the resistance set to a low level. You should
then stretch the muscles you’ve just worked to develop flexibility, reduce muscle soreness and
prevent injury.
Increase your work-out time by a few minutes each week until you can work continuously for 30
minutes per session.
Don’t worry about distance or pace for the first few weeks, focus on endurance and conditioning.

HOW HARD SHOULD YOU WORK?
When exercising, you should try to stay within your target heart rate (THR) zone.
The table on the previous page will tell you the THR for your age.
Always be aware of how you feel when you exercise. If you feel dizzy or light-headed, stop immediately
and rest.
STRETCHING GUIDE
TIPS FOR STRETCHING
Begin with small mobility exercises of all the joints e.g. simply rotate the ankles, bend the knees and
roll your hips. Gradually make the movements larger and faster. This will allow the body’s natural
lubrication (synovial fluid) to protect the surface of your bones at these joints.
Always warm up the body before stretching, as this increases blood flow around the body, creating
warmth which makes the muscles more supple
Start with your legs, and steadily work up the body.
Each stretch should be held for at least 10 seconds (working up to 20 to 30 seconds) and usually
repeated about 2 or 3 times.
Do not stretch until it hurts. If there’s any pain, ease off.
Don’t bounce. Stretching should be gradual and relaxed.
Don’t hold your breath during a stretch.
Stretch after exercising to prevent muscles from tightening up.
Stretch at least three times a week to maintain flexibility.
WARM-UP and COOL-DOWN
A successful cardio-vascular exercise program consists of a full body warm-up, aerobic exercise, and a
cool-down. Do the entire program at least two and preferably three times a week, resting for a day
between workouts.After several months, you can increase your workouts to four or five times per week.
WARM-UP
The purpose of warming up is to prepare your body for exercise and to minimize injuries. Warm up for
five minutes before strength-training or exercising aerobically. Perform activities that raise your heart
rate and warm the working muscles. Activities may include brisk walking, jogging, jumping jacks, jump
rope, and running on the spot. Try to incorporate moves that take the joints through their full range of
motion.

- 16 -
STRETCHING
Stretching while your muscles are warm after a proper warm-up and again after your strength or aerobic
training session is very important. Muscles stretch more easily at these times because of their elevated
temperature, which greatly reduces the risk of injury. Stretching develops flexibility and reduces muscles
soreness.
Stretches should be held for 15 to 30 seconds.
DO NOT BOUNCE OR OVER-STRETCH. Take your time in each stretch. Gradually take each
stretch a little deeper on every out breath to your personal maximum.
Remember always to check with your physician before starting any exercise program.
COOL-DOWN
The purpose of cooling down is to return the body to its normal or near normal, resting state at the end of
each exercise session. A proper cool-down slowly lowers your heart rate, allows blood to return to the
heart and helps prevent muscle soreness caused by the build-up of lactic acid in the muscles.
