OK, I know some of you guys cringe at the thought of a squat. You may hate doing them because they are hard. You may hate doing them because you don’t have adequate hip mobility, or lack mobility in other areas that effects the movement chain. Both of these things can be fixed with a little work (well, actually that is only half true); they are always going to be hard if you are doing them right. However, there may be a third reason that that you dread squats, which is that you are just not built for them, and this is not something you can change.
Mike Boyle touched on this in his lecture and provided a reference, which inspired me to research it further. Although I was aware people had different pelvis and femur structures, it was always more of a vague afterthought for me. After seeing the evidence in pics and doing a little more research, I now have a clearer understanding of how bone structure of the hip and femur effects squatting ability.
Take a look at the two femurs in this picture. The structure of the heads are very different. This causes them to fit into the hip sockets differently, and at different angles. The hip sockets of different individuals can also have very different structures. Here is a link to an article which was referenced in the lecture, which I think you will enjoy if you find this interesting:
So those who feel the need to squat with a wider stance, or with toes outward versus straight ahead, or are unable to go as deep as others, may have structural reasons behind these things that makes certain stances and variations a better choice for them; just something to consider.
Although I would still make it a priority to work on having good hip mobility and strong legs that can push weight and support you, we will also listen to what your body is telling you and let it guide you in doing squats in the best way for you.
