I wish I was looking for some specific advice; it would probably make it easier. Training alone, I'm pretty much left up to my own to figure out what's going on in my lifts, but I've reached the limit of my ability to look at it myself and compare it to what I see and read online, so I'm hoping there's something that stands out to the guys here.
I do agree my hips start up first and I'm not sure what the reason is. Whenever I squat using the form in the video, they always start first, even with warm up weight. If I try to widen my feet and sit back more, it looks better, but I have to really arch my lower back to keep my back from ending up horizontal, but then I run out of room and can't reach parallel.
I'm definitely more comfortable squatting like in the video, so I guess I'm wondering if there is something specific, like my quads, which was suggested, that is holding me back, or if I need to re look at my whole technique.
Thanks for the help!
