I think everybody should be able to 3rd world squats!
2 years ago I couldn’t squat below parallel, today I can squat hamstrings to calves but still got a lot of work to do.
You just need to focus on ankles, knees and hips.
Smashing the quads, rectus femoris and high adductor helps tremendously.
And working on hip flexion, smashing the gut, hip flexors, tfl, glutes.
