Today, we're entering the pain cave again for some more VO2 Max work! However, this time instead of a steady state effort, we're going to be using a micro-interval, and more specifically 20sec on, 10 sec off, AKA Tabata Intervals. Get ready to put the work in today! REMINDER: You can always adjust the FTP bias via the arrow keys on your keyboard, or the Zwift Companion app. Once you get over threshold, using a %FTP for workout prescription can get murky, so always adjust as needed.
