Are we really still debating the best way to track progress on a dumb trainer, or has the collective IQ of the cycling community finally sunk to the point where we just resort to guessing whether were getting faster or not. Given the simplicity of the technology, why do so many of you seemingly intelligent individuals struggle to grasp the fundamental concept of tracking progress on a dumb trainer. Is it really that difficult to understand that using a dumb trainer with no power or speed data output means you have to get creative with how you measure progress. How do you guys actually think youre getting any meaningful data from these archaic devices, or are you all just content with making educated guesses based on perceived exertion levels. Do none of you have even the most basic understanding of math and physics, or are we just Luddites who refuse to accept that our precious dumb trainers are essentially useless for tracking progress without some serious DIY ingenuity. If youre not using some combination of heart rate, cadence, and manually recorded interval times, are you even really training at all. Can someone please, for the love of all that is holy, explain to me why so many of you are still stuck in the dark ages of training with dumb trainers and no real way of tracking progress.
