I’m from the rural southern Midwest of the US, and could always deep squat. I have laxed tendons $ ligaments from a connective tissue disorder, & that’s what allowed me to do a deep squat with no history of the stance. Those laxed tendons & ligaments were also what kept me from sustaining the stance. I was very unstable.
Tangent: I’d go hunting with my family during the winter, and being female made peeing tricky. I had to take my winter clothes off, then hold onto a fence or tree to owe, and with my stubby legs, my girly bits would always touch the grass, ice and snow.
Now that I’m in my 50’s, and decades of muscles overcompensating to try and keep me stable, plus arthritis in my right ankle due to breaking tibia and fibula, I’m not comfy in that position. I’d like to find a way to go it again, but arthritic ankles can be tricky in a deep squat. How do the elderly do it?
