Well, I kept trying to squat like most people do trying so hard not to lean forward and kept falling over on my ass lol. That and also I couldn’t feel the work in my glutes, only quads. Are you familiar with the way little children squat? I still can’t do it but getting better every day by practicing.
Turns out I have super tight hips and that prevented me of hinging correctly, plus the aformentioned femur/torso ratio.
I hired a personal trainer in january of this year to help me out with stuff and she helped me correct my form. Now I use a pair of those foam wedge things under my heels to prop me up in a better position and I can squat way better. It was a game changer.
Good for you OP! Spanish is such a rich, beautiful sounding language.
My best bet, aside from full immersion is to first, take lessons in order to learn good foundations and know how stuff works and then, hire a language coach who can help you with your specific request.
