Bodyweight Squats are often used as an entry level exercise but in this exercise hierarchy they are deemed a more complex exercise than any of the entry-level Front Loaded Squat derivatives owing to the lack of constraints on lumbar spine posture. In saying that there are uses for the bodyweight squat.
As coaches interested in developing movement competency for sports performance, we have an opportunity to view the Squat pattern under similar conditions to the majority of sports performance- unconstrained and free of additional external load.
Can your athlete Squat with competency without external load forcing them through a range of motion? Does the lumbar spine posture remain constant as the hips, knees and ankles flex and extend? If not, our direction is to return to the Corrective Phases of Squat training, constrain the lumbar spine and address range of motion and coordination deficiencies before progressing through the hierarchy.
