In lower crossed syndrome, certain muscle groups become overactive or tight while others become underactive or weak. The condition is characterized by particular patterns of muscle imbalances, primarily involving the hip flexors, lumbar extensors, abdominal muscles, and gluteus maximus.

The deep cervical spine flexors are not typically affected or facilitated in lower crossed syndrome because this syndrome primarily emphasizes the lower body and lumbar region, not the cervical region or neck muscles. The cervical spine muscles, including the deep cervical spine flexors, are outside the scope of the primary disturbances seen in lower crossed syndrome, which focuses more on the relationship between the hip flexors and lumbar extensors in the context of the overall posture and stability of the lower body.

In contrast, the iliopsoas, gastrocnemius, and lumbar portion of the erector spinae are linked to this syndrome, showcasing the imbalance whereby the iliopsoas and lumbar extensors become overactive while the glutes and abdominal muscles tend to be underactive. Recognizing the specific role of each muscle group in this syndrome helps in designing effective rehabilitation or training programs aimed at correcting these imbalances.
