Physiological stories provide a valuable "why"
I prefer it when a training idea is combined with a physiological explanation.
Even if the explanation is not true, I still want to have a rationale for training.
It helps to know the why behind what you're doing.
If the training plan doesn’t help performance, I'll forget the explanation pretty quickly.
But if it does help performance, then at the very least the physiological explanation serves as a motivating story.
The explanation may still be incorrect, but the mechanism is probably at least correlated with something that is correct.
Performance remains the ultimate judge.
Focus first on performance and tracking what works for you.
