W ARM-UP AND COOL-DOWN
A successful exercise program consists of a 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 PHASE
The purpose of warming up is to prepare your body for exercise and to minimize injuries. Warm
up for two to five minutes before strength-training or aerobic exercising. Perform act ivities that
raise your heart rate and warm the working muscles. Activities may include brisk walking,
jogging, jumping jacks, jump rope, and running in place.
STRETCHING
Stretching while your muscles are warm after a proper warm-up and agai n 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. Stretches should be held
for 15 to 30 seconds.
DO NOT BOUNCE.
Remember always to check with your physician before starting any exercise program.
EXERCISE PHASE
This is the stage where you put the effort in. After
regular use, the muscles in your legs will become
more flexible. Work at your own pace and be sure to
maintain a steady tempo throughout. The rate of work
should be sufficient to raise your heartbeat into the
target zone shown on the graph below
COOL-DOWN PHASE
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 and allows
blood to return to the heart.
