Is the polarized training approach truly the ultimate way to improve cycling performance, or is it just the latest trend in the cycling world, and if its as effective as proponents claim, why do so many professional cyclists still achieve success with more traditional training methods, and what specific physiological benefits does polarized training offer that other approaches dont, and how can cyclists effectively balance the need for intense interval workouts with the risk of overtraining and injury that often comes with it, and are there any potential drawbacks to polarized training that are being overlooked in the enthusiasm for this approach, and can cyclists who dont have access to expensive training software and heart rate monitors still benefit from polarized training, or is this approach only suitable for elite athletes with unlimited resources.
