The deep squat (aka full squat, aka ass to grass/ATG squat) is one of the most debated, talked about exercises/assessment we have in human movement. Some talk about the deep squat as if it’s the cure to cancer, some talk about it like it’s going to cause the apocalypse. I have found that I always get mixed information and many take either a full medical approach, a full evolutionary approach, or a full performance approach.
