Getting Your FTP Estimate
Before you can get your Functional Threshold Power (FTP) estimate, you must pair a chest heart rate monitor and power meter with your device (Pairing ANT+ Sensors), and you must get your VO2 max. estimate for cycling (About VO2 Max. Estimates).
The device uses your user profile information from the initial setup and your VO2 max. estimate to estimate your functional threshold power (FTP).
