Question

what happens when we sit with the back hunched or bend

Answer 1

A flat back means your pelvis is tucked in and your lower back is straight instead of naturally curved, causingyou to stoop forward. ... Spending long periods sitting down can also contribute to a flat back. A flat backalso tends to make you lean your neck and head forwards, which can cause neck and upper back strain...
