OK. I'm listening now. That guy's got a hinge in his spine worse than a road cyclist. He needs to door some core work.

His back is flexing very sharply at one point in his vertebral column, which is unusual and not what your back is supposed to do. It's supposed to spread flexion of the trunk more evenly between all the intervertebral joints - differently between different functional areas of the spine, but similarly within those areas. A 'hinge' is something that is very common in road cyclists, because they want to sit squarely on a flat seat, keep their hips posteriorly tilted to get more power from their glutes when pedaling, which keeps their lower back straight and stretches their hamstrings less, but they also want to keep their upper body as aerodynamic as possible and rest the weight of their upper body on passive structures, like ligaments as much as possible to reduce the amount of energy they use from muscle contraction in the upper body. It develops hypermobility, and hence, instability in a small number of joints in the vertebral column, usually at the top of the lumbar spine, and can wear out or damage the discs in those joints, because all the pressure is on the front of the disc. They get this sharp corner in their back - a hinge - rather than a gradual curve. It's potentially very damaging and can cause severe degeneration and pain later in life. By training the abdominals and postural muscles in the trunk and abdomen - the 'core' of the body - they can maintain a higher internal pressure, better supporting the vertebral column in a healthier, more biomechanically sound position and reducing the chance of damage and degeneration. It's a concept of training and protecting the body that has evolved independently in many different areas, times and cultures, so it is something like the Darwinism of physical performance and structural health. Those bodies who support their spine more effectively tend to have longer-lasting and healthier bodies. Those who 'hinge' can develop severe problems sooner and lose function earlier.

Finally read this, and my face was definitely page 21
