I'm not sure who thought it would be a good idea to post videos of squats and deadlifts on the internet to get a "form check". This almost always turns out to be the blind leading the blind, and even when it isn't, has anyone actually made their form "better" by reading a list of generic form cues? What does "better" even mean? Do people even have a benchmark in mind when they ask for advice, or are they just giving in to their own neuroses?
"Better form" is the leprechaun of internet fitness communities. Want a better squat? Get under the bar and practice it until you can handle over double body weight. Better pull? Pick the thing up. Figure out how your body wants to move under load. It can move just fine without "expert" biomechanical advice. Doing the thing and paying attention to what happens is more valuable than any internet checklists.
