Conducting an FTP Test
Before you can conduct a test to determine your functional threshold power (FTP), you must pair a chest heart
rate monitor and a power meter with your device (
Pairing Your Wireless Sensors, page 83
), and you must get
your VO2 max. estimate (
Getting Your VO2 Max. Estimate for Cycling, page 45
).
NOTE: The FTP test is a challenging workout that takes about 30 minutes to complete. Choose a practical and
mostly flat route that allows you to ride at a steadily increasing effort, similar to a time trial.

Fitness Goals
Knowing your heart rate zones can help you measure and improve your fitness by understanding and applying
these principles.
• Your heart rate is a good measure of exercise intensity.
• Training in certain heart rate zones can help you improve cardiovascular capacity and strength.
If you know your maximum heart rate, you can use the table (
Heart Rate Zone Calculations, page 52
determine the best heart rate zone for your fitness objectives.
If you do not know your maximum heart rate, use one of the calculators available on the Internet. Some gyms
and health centers can provide a test that measures maximum heart rate. The default maximum heart rate is
220 minus your age.
About Heart Rate Zones
Many athletes use heart rate zones to measure and increase their cardiovascular strength and improve their
level of fitness. A heart rate zone is a set range of heartbeats per minute. The five commonly accepted heart
rate zones are numbered from 1 to 5 according to increasing intensity. Generally, heart rate zones are
calculated based on percentages of your maximum heart rate.
