Get FIT with the IMAGE 14.6Q.
Effective aerobic exercise has three major parts:
frequency
,
intensity
, and
time
. The acronym "FIT"
may help you to remember these three parts:
“F” stands for the frequency of your workouts.
Three to five workouts per week are recom-
mended. Exercise at least four times a week for
weight loss.
“I” refers to the intensity of your workout.
Check your heart rate at least twice during
your aerobic exercise session: once during the
session and once again at the end. Maintain a
workout intensity level within your Target Heart
Rate Zone. You can measure your heart rate
using the hand pulse sensor or the chest pulse
sensor.
“T” is for the time or duration of your workout.
Beginning exercisers may wish to start with 5
to 10 minutes of aerobic activity. Those in aver-
age physical condition should exercise for 20 to
30 minutes. Highly fit people, or people who want
to lose weight, should exercise for 30 to 60 min-
utes. The key to the time factor is that you main-
tain your target heart rate for the duration of the
workout period.
Remember to take it slowly. Fitness is a lifelong
commitment. If you can't go the full 20 minutes
from the start, which is common, try to exercise
for five minutes at a time, a couple of times a day.
Recent research indicates that several short
workouts in one day can also provide fitness
benefits. Gradually, your stamina will increase
and it will become easier to exercise for longer
periods of time.
Cool down after aerobic exercise.
Keep moving! It is important that you cool down
properly to allow your heart rate to decrease
slowly after it has been elevated. This helps the
blood flow from your extremities back to your
heart. Keep your legs moving on the treadmill at a
slower pace for at least five minutes following the
aerobic phase.
Stretch again at the end of your exercise
session.
Stretching after exercise reduces muscle sore-
ness. See step 5 on page 27.
Participate in strength training.
"Balanced fitness, including both strength training
and aerobic exercise, can do more to ensure a
happy life than just about anything else known to
medical science today."
—Kenneth Cooper, M.D., M.P.H., founder of The
Cooper Institute For Aerobic Research, Dallas,
Texas.
A strength-training program increases your lean
muscle mass. Lean muscle mass aids in burning
body fat. With additional muscle mass and
strength, you will receive the full benefits of an
exercise program. You will also be less prone to
injuries during the aerobic phase of your workout.
