while that analogy isn't a perfect one to explain the situation with thin spines versus thick spines I think it gives you a mental image of the general situation for which some people who have the more Willow like spine probably need to build more musculature around the spine in order to stabilize it but probably don't have to do quite as much work in order to generate more side to side flexibility as opposed to people who have a thicker spine who probably don't need to do quite as much work to develop the musculature of the spinal Erectors of the abdominals it's not to say they don't need to develop those at all they do but that they don't need to do quite as much work to build the musculature around the spine in order to stabilize it for vertical loads but they perhaps want to do more work aimed at generating more flexibility in these planes of motion from side to side and at different angles you know relative to the vertical axis
