In the lower-crossed syndrome, which two muscle groups are typically weak?

In lower-crossed syndrome, the primary muscle groups that are typically weak are the glutes and the abdominals. This condition is characterized by an imbalance between the lower back and hip muscles, often resulting in tightness in certain muscle groups and weakness in others.

In this syndrome, the gluteal muscles, which are crucial for hip extension and stabilization, tend to be underactive or weak. As a result, they do not adequately counterbalance the overactive hip flexors, leading to altered pelvis positioning and potential lower back pain. Similarly, the abdominal muscles, especially the rectus abdominis and the obliques, are also weak. This weakness fails to provide sufficient support to the pelvis and lumbar spine, further contributing to the dysfunction associated with lower-crossed syndrome.

The condition typically leads to a characteristic pattern of tight and weak muscle groups that can influence functional movement patterns. Strengthening the glutes and abdominals is essential in correcting the imbalances present in lower-crossed syndrome, which helps restore proper pelvic alignment and improve overall movement efficiency.
