I squat high bar with a shoulder-width stance and always aim for ass-to-grass squats. I always felt like I was falling forward and unstable ascending in the squat. The weight always felt like it was concentrated on my quads and knees rather than being hip-dominant.
So yesterday I tried putting plates underneath my heels to try and simulate the heel lift of olympic weightlifting shoes. Though it felt awkward stepping on something else on the walkout of the squat, I instantly felt more stable going up and actually felt myself using my hip and glutes more to accomplish the squat. Needless to say, I now find myself more comfortable with plates under my heels than just flat feet.
I'm asking for advice on how to proceed after this since just I've been squatting and reading about the technique for about half a year now, and this is getting complicated. Taking note of my first "version" (no plates) of the squat, do I have mobility problems, and if so, can I work on them to improve my technique/pattern? Are there any squat cues that can help? Or should I invest in squat shoes since I seem to be more comfortable in raised heels?
Thank you! Any feedback would be appreciated!
