Habitual postures can also lead to muscle imbalances. A person may be sitting at their desk all day slouching forwards, which can lead to tight hip flexors and lengthened/weak glute muscles. Tight hip flexors can lead to a lack of hip extension range of motion, thus driving an issue at the back. Because the body likes to find ways around restrictions, this person might compensate with excessive mobility at the low back joints to make up for that lack of hip mobility. Over time, changes in these tissues structures can ultimately become a source of pain.
