Don`t get too down on yourself, I think we have all gone through this same situation that you are in. It takes a while to develope a good squatting stance that is truly functional for the desired effect. The main muscles to be worked when squatting are the quads, then the glutes, then the lower back, etc. It will take you some time to develope the proper body position, foot position, and depth, for your type of body.
We all have different builds from which to work, and it takes a while to "mold" yourself into someone that can squat safely, and produce the desired results. When I first started, I hated squatting, but the more I worked at it, the , more I like it. I think it
s all relative to getting the entire body used to squatting first, by doing lots of reps with light weight, and once youve developed your " squatting zone", then you can start adding plates, and get the benefits that squatting gives us. Hope this helps.
