Tight thoracolumbar extensors lead to which of the following?

Explanation:
Tight thoracolumbar extensors pull the spine into excess extension and tend to tilt the pelvis forward (anterior tilt). This pelvic position shortens the hip flexors, so they become tight from chronic shortening. In this pattern, the back stays stiff and extended, while the front of the pelvis (where the hip flexors attach) remains shortened and tight. The other ideas—weak abdominals, weak gluteus maximus, or the same tightness as the back extensors—don’t capture the direct consequence of this postural imbalance as clearly as the development of tight hip flexors.
