Whats the general consensus on the benefits of using dumb trainers for high-intensity interval training (HIIT) - do they truly offer a superior workout compared to smart trainers, or is it just a case of trainers are trainers and the HIIT benefits are more down to the riders effort than the equipment itself. Ive seen some arguments that dumb trainers actually force riders to focus more intensely on their own cadence and power output, which could potentially lead to more effective workouts and increased muscle memory. On the other hand, smart trainers often come equipped with built-in workouts and training programs tailored to specific goals and rider levels - do dumb trainers offer the same level of customization and adaptability. Is the lack of real-time feedback and data analysis a major drawback for dumb trainers in the context of HIIT, or are there ways to effectively integrate data tracking and analysis into dumb trainer workouts. Are there specific types of riders or training goals that are better suited to dumb trainers, and conversely, are there situations where smart trainers are the clear superior choice.
