The full read
No named study supports this kind of dose-response relationship between how deep a stretch goes and back pain prevention; it sounds plausible but doesn't match any trial identified in the spinal-mobility literature. What is established actually cuts against the 'deeper is better' idea: reviews on static stretching and injury prevention (Small et al., 2008; Lauersen et al., 2014) find no protective effect from stretching in general, regardless of intensity reached, and greater joint laxity isn't consistently associated with less pain — in some contexts, hypermobility is even linked to more instability. The post cites no source or mechanism, just a personal experience generalized into a universal rule. Spine mobility itself is a reasonable goal for feeling better day to day, but the specific claim of a proportional link to back pain prevention isn't verifiable given the available data.
