With the weakening of the abdominal wall, another sensitive area is weakened in our body: the waist. Since the weakened abdominal wall no longer supports the lumbar spine from the front, we might face waist pain more often.
85-90% of waist pain is caused by weak abdominal wall (that can be a relative weakness, when the abdominal wall is weaker compared to the muscles supporting the spine).
Your waist is supported by this muscle group from the front. If it is weak, the support fails.
