Frequently asked questions

How do I measure my FTP?
The most common method is a 20-minute all-out time trial; multiply average power by 0.95. Alternatively, use a 60-minute all-out test (average power = FTP directly). Structured ramp tests (e.g. Zwift Ramp Test) are also popular.
Which zone is best for weight loss on the bike?
Zone 2 (endurance, 56–75% FTP) maximises fat oxidation and builds aerobic base with low recovery cost. Long Zone 2 rides are the foundation of most cycling programs.
