I started this plan on Zwift called FTP Builder. Today, I finished week #1. The plan's first week had two hard workouts, Strength and Tempo, and two easier workouts called Foundation.
I was able to finish one minute at 320 Watts. The new FTP indicated was 241 Watts.
This test should be done maximum once per week.
