A “squat” is a weight-lifting exercise that begins while standing upright with a barbell supported on the shoulders. The knees are flexed and then extended, trying to keep the back fairly straight upright. In terms of torques, moment arms and muscle forces, why is it more difficult to do a full, deep squat compared to a “half squat” in which you only squat down part way before rising?
It is difficult to do full deep squat because as the exercise itself has so many constraints as it is mentioned in the question that the knees are to flexed and extended , back needs to be straight upright. When you try to do a full squat you are bending your knee completely and your whole upper body weight is is only on one side pulling you backwards , a torque is generated along your hips when you try to go down , this torque has an angular momentum if a person has strong thigh muscles he /she can easily counter that angular momentum while coming up since the whole body weight is backwards it will be difficult for any person with weak thigh muscles to rise up to a standing position.
