Negged. How dare you speak ill about Rippetoe. J/K
Great video. I utilized Starting Strength as a reference when learning to squat. And I made both of the mistakes you discussed. Learned the hard way how to not make those errors. To me the Gem in your Squat philosophy that can help everyone, is the idea that one should find a form that feels natural (hope I'm not butchering that). That concept has really helped myself and I think it is really the golden ticket.
Lastly, I've noticed that new squatters using the ripptoe method tend to take a stance that is too wide. Just another observation.
