There's no single 'correct' spine position for every lift

The spine can safely handle a range of positions under load - rigid rules oversimplify a flexible system

Lifting advice often treats a 'neutral spine' as an absolute, non-negotiable rule for every exercise, as if any deviation guarantees injury. Biomechanics research paints a more nuanced picture: the spine is a flexible structure capable of tolerating meaningful load across a range of positions, and elite lifters in sports like weightlifting and strongman routinely round or flex their spine under significant load without it causing harm, because their tissues have adapted to those specific positions and forces gradually over time.

What actually predicts injury risk isn't a single degree of spinal flexion in isolation, but a combination of factors: how quickly load is added to an unfamiliar position, total cumulative load and fatigue, and whether the movement pattern is one the person has trained and adapted to versus one they're doing for the first time under real weight. A perfectly neutral spine with poor overall movement control and fatigue management isn't automatically safer than a well-conditioned lifter working in a braced, controlled flexed position.

For most people learning to lift, defaulting to a neutral spine is still sound practical advice - it's the safer default while building the tissue tolerance, technique, and body awareness that let more experienced lifters deviate from it without issue. The point isn't that spine position doesn't matter; it's that rigid, universal rules oversimplify a system that actually adapts.
