FTP represents the highest power you can sustain for one hour and is the foundation for setting training zones, pacing strategies, and metrics such as watts per kilogram, normalized power, and intensity factor. Raising FTP allows you to ride faster for longer without crossing your lactate threshold, boosting climbing ability, sustained speed, and overall endurance.  See how here:https://www.pacelinebikes.com/how-to-improve-ftp-through-cycling-training-and-progressive-overload/
