I'd also add Jeremy Ethier for the highest production value videos I've comes across, which typically include insights from research in the flow of the video, and which use nice overlay 'explainer graphics,' which make it easier to understand his detailed breakdowns of muscle-targeting, desired motions/angles etc.

Here's an example where he's talking about developing strength to get your first pull-ups: https://youtu.be/3YvfRx31xDE?t=75

Great source for problem solving specific issues that come up in strength training.
