Q. Is a back that is too flat also a problem, the opposite of a rounded one?
A flat back is a problem too. The pressure on the disc when bending forward is higher than usual.
📝 Detailed Answer
When the pelvis tilts backwards and the curves of the lower back and upper back reduce so that the back looks flat, this is called flat back, or a flattened lumbar curve.
In this case the pressure pushing the disc towards the back of the waist as you bend forward is higher than normal, so marked low back pain can come with it.
In other words, "a straighter back is always better" does not always hold. We measure what the state is now and then set the direction.
