Fitness content splits cleanly into two kinds that share a shelf and should not. One teaches: it names the mechanism, shows the movement, states the numbers, and tells you what to do differently on Monday. The other performs: it walks through a session in real time, and what you take away is motivation rather than method.

Both are legitimate. Only one of them is what you wanted when you searched for how to fix your form.

This ranking is by measured value density, which favours the instructional kind for a structural reason rather than a taste one — a video that repeats a cue eight times across a set adds little after the first. Entries carry a difficulty level, because a video pitched at a first-year lifter and a video assuming you already periodise are not competing for the same hour.

Two things this page does not claim. It is not medical advice, and a high density score is a statement about how much a video says per minute, not about whether the protocol inside it is right for your body or your history.

Yes, 8-12 is needlessly narrow: studies suggest roughly 5-50 reps per set grow muscle similarly, but keep 50-70% of training at 5-12 reps since failure is hard to gauge above 12.
