Whats the point of using TrainerRoads power zone-based training when the FTP test protocol is so unreliable and open to manipulation, and how can a beginner trust that their workouts are tailored to their actual abilities when the entire system is based on a flawed FTP estimate, and why do people still swear by TrainerRoad when other training platforms offer more flexible and nuanced approaches to intensity-based training, and is it just me or does anyone else find it ridiculous that TrainerRoad still uses a 20-minute all-out effort as the gold standard for estimating FTP when its been widely criticized for being both physically and mentally exhausting, and whats to stop a beginner from just faking it and riding at a perceived exertion thats not actually reflective of their true fitness level, and why do TrainerRoad coaches and trainers still insist on using this outdated and simplistic approach to training when its clear that a more holistic and multi-faceted approach would be more effective, and whats the deal with all the hype around TrainerRoads science-backed training plans when its clear that theres a lot of pseudoscience and bro-science going on behind the scenes, and why do people still shell out big bucks for TrainerRoads premium features when you can get similar functionality from other platforms for a fraction of the cost, and whats the endgame here - is TrainerRoad just trying to make a quick buck off of gullible cyclists or is there actually some substance to their training methodology.
