Exercise Guidelines
Check with your physician before beginning any type of exercise program.
People who have diabetes or high blood pressure, a family history of heart disease,
high cholesterol, any other special medical condition, are over age 35, or have led a
sedentary lifestyle should get a medical check-up and a stress test before initiating an
exercise program or routine. Medical research has shown that the optimal amount
of exercise to condition the cardio respiratory system and the muscles of the body is
between 60% and 85% of your maximum heart rate, as measured during a training
session.
If at any time during exercise you experience dizziness or chest pain, stop
immediately and seek medical advice.
Target Heart Rate Zone Formula:
220 minus your age multiplied by your desired Heart Rate Zone Goal (suggested by
your doctor) = your target heart rate BPM.
Do not workout at your maximum heart rate. The recommended heart rate zone is
between 60% and 85% of your maximum heart rate.

Warm Up and Cool Down
A successful exercise program consists of a warm-up, aerobic exercise, and a cool-down.
Warming up is an important part of your workout and should begin every session. It prepares your
body for more strenuous exercise by heating up and stretching out your muscles. At the end of
your workout, repeat these exercises to reduce sore muscles. We suggest the following warm-up and
cool-down exercises:
HEAD ROLLS
Rotate your head to the right for ten seconds, feeling the stretch up
the left side of your neck. Next, rotate your head to the left for ten seconds.
Finally, drop your head to your chest for ten seconds.
SHOULDER LIFTS
Lift your left shoulder up toward your ear for ten seconds. Then lift
your right shoulder up for ten seconds as you lower your right shoulder.
SIDE STRETCHES
Open your arms to the side and continue lifting them until they are
over your head. Reach your right arm toward the ceiling as far
as you can for ten seconds. Feel the stretch up your right side.
Repeat this action with your left arm.
