What best describes a lack of core and gluteal strength during squats?

1. Glute dominance

2. Hamstrings dominance

3. Quadriceps dominance

4. Lumbar dominance

The correct answer is: Lumbar dominance

A lack of core and gluteal strength during squats is best described by lumbar dominance. When an individual lacks strength in the core and glute muscles, the lower back (lumbar region) often compensates for this weakness. This compensation can lead to an exaggerated arch in the lower back and an increased reliance on the spinal muscles rather than the stronger, more powerful muscles in the core and glutes. As a result, the movement pattern becomes less efficient and can increase the risk of injury over time. In contrast, glute dominance would imply that the glutes are taking the lead during the squat, which is not the case when strength is lacking in that area. Hamstring dominance indicates that the hamstrings are doing most of the work instead of the intended muscle group. Quadriceps dominance suggests that the quadriceps are overly engaged in the squat, which can detract from the effectiveness of the exercise if not balanced. Therefore, lumbar dominance is the most accurate descriptor of the situation where core and gluteal strength are insufficient.
