FITNESS TEST (FTP TEST)
Your Newton+ includes a built-in, power-based fitness test that measures your cycling
fitness. It is a very simple test: you ride as hard as you can for 20 minutes. Then, the
Newton+ computes the average watts you held during the test, divided by your body
weight in KG. This "Watts per kilogram" ratio is a simple and critical measure of cycling
fitness. Simply put, the higher your watts per kilogram the more fit you are and the faster
you'll go.
Also, the average watts held during the Fitness Test, times the multiplier of 0.95, is an
excellent measure of your Functional Threshold Power (FTP). FTP is used by most experts
as a key measure of your overall aerobic limit and cycling fitness.
The Newton+ firmware includes a table developed by professional racer and noted cycling
coach Boyd Johnson that interprets your W/KG score as a fitness level from one to ten.
Your fitness level is based on your W/KG measurement and your sex. Here is the table
that is loaded into the Newton+ firmware:
Fitness

10
So, for example, if you are male and your 20 minute test returns a W/KG measurement of
2.48, then your fitness level is "3" (the female would score a higher fitness level of "4" for
the same W/KG result).
What can you do with this test? Three things:
1) You can use the test result to provide you and objective and meaningful assessment
of your current level of cycling fitness
2) You can use the test result in conjunction with built-in fat burning, cardio, and
strength workouts that are targeted to your specific level of fitness. These workouts
will help you improve your cycling fitness quickly and efficiently. The workout
feature is described in the next section
3) You can repeat the fitness test during the season, and quantify the improvements
achieved by your cycling efforts
At the end of the 20 minute test your Newton+ will show you your test result, expressed
