Which muscle is commonly tight in individuals with hyperlordosis?

Individuals with hyperlordosis often exhibit tightness in the iliopsoas muscle. Hyperlordosis is characterized by an excessive inward curvature of the lumbar spine, which can lead to altered postural mechanics. The iliopsoas, which consists of the iliacus and psoas major, plays a crucial role in hip flexion and stabilizing the lumbar spine.

When hyperlordosis occurs, the iliopsoas can become shortened and tight due to its engagement in maintaining the exaggerated curvature and the habitual hip flexed position. This tightening can contribute to lower back pain and discomfort, as it places increased stress on the lumbar vertebrae and surrounding musculature. Additionally, the tightness in this muscle can limit hip extension, further exacerbating the postural imbalance associated with hyperlordosis.

In contrast, other muscles listed may not show the same level of tightness in this condition. For instance, the rectus abdominis is typically weaker in individuals with hyperlordosis, as it is often overshadowed by stronger hip flexors like the iliopsoas. The gluteus maximus generally works to counteract excessive lordosis and may not be tight. The quadratus lumborum, while involved in lateral flexion and
