In a QM squat ("accroupetonnement"), like in a bipedal squat, the body is lowered and the legs fully flexed. The main difference is that one or both hands are touching the ground. The legs still support most of the weight of the body, the arms providing mostly increased stability and sometimes additional support. The squat has several variants as seen on the illustrations, depending on the relative location of the hands and feet. QM squats with the hands behind or sideways are not very common, but should be trained to become natural. QM squats are mostly a starting posture for other exercises such as holds and jumps, or a transition posture between them. It is also a useful posture for hiding, resting and waiting.
For most civilized people, this position is quickly painful and hard to hold. On the contrary, many primitive peoples use QM squats as a regular resting pose. [Note: Georges Hébert, as a man of the early 20th century, saw the world as divided between "civilization" and "primitive" peoples. However, he was also very impressed by the natural fitness of those primitive peoples and very critical of the civilized world's view on physical activity. Although "primitive" has a negative connotation, it is seen here as a quality, so I kept those terms.]
The huddled QM squat ("blotissement") is a full QM squat, with round back, knees to the chest, often with the arms around the legs. Like in the regular QM squat, there are different variants based on the hand and feet position. To get into any of these, one must start by getting into the corresponding QM squat and then lowering and rounding the body into the huddled form. To stand up from the back and side huddle, it is possible to use a rocking of the body, kicking one or both legs out to increase momentum.
