Most deadlift issues can be traced back to an improper setup. Unfortunately there’s no “one size fits all” and your setup position will be dictated by how you’re built and how some specific, diagnostics points come together. All three lifters in the picture are in a proper deadlift position for their anthropometry, but all of them may look distinctly different. Rip explains further in blue book:
“The question of exactly what the three reference angles should be is answered for each person individually since it depends on individual anthropometry. People with long femurs, long tibias, and relatively short torsos will have a more horizontal back angle and a more closed hip angle than people with long torsos and short legs, who will have a more vertical back angle and a more open hip angle. Each person will have a different set of knee, hip, and back angles, but the correct starting position for everyone will have the previously discussed things in common: the shoulders will be slightly in front of the bar; and the bar will be touching the shins directly over the mid-foot, resulting in the vertical alignment of the scapula, bar, and mid-foot. If this alignment is correct, and if the arms are straight, the feet are flat on the floor, and the back is in good thoracic and lumbar extension, the resulting reference angles are correct for that person’s anthropometry. Of the three angles, the back angle will exhibit the most obvious individual variability, easily seen by an informed observer.

Arm length must also be considered when you are analyzing these angles. All other segment lengths being equal, short arms produce a more horizontal back angle and long arms produce a more vertical back angle. Long arms tend to mitigate the effects of a short torso, while short arms and a short torso make for a nearly perfectly horizontal back. To balance the effects of short arms and a short torso, people with this very unusual build might need to use a sumo stance, since a wide stance produces the more vertical back angle typically seen in people with more typical proportions.”

Effects of Stretching or Strengthening Exercise on Spinal and Lumbopelvic Posture: A Systematic Review with Meta-Analysis

👉 Stretching of skeletal muscles with restricted ROM represents one of the most popular strategies used to tackle muscle imbalance and postural impairments (https://pubmed.ncbi.nlm.nih.gov/22223616/).

👉 As early as 1997, Spring et al. (https://pubmed.ncbi.nlm.nih.gov/9490434/) recommended it as the gold standard of posture treatment, but convincing evidence for this recommendation is lacking until now.

🤔 A brand-new meta-analysis by Warneke and colleagues (https://sportsmedicine-open.springeropen.com/articles/10.1186/s40798-024-00733-5) examined the effect of stretching or strengthening on spinal and lumbopelvic posture (e.g., pelvic tilt, lumbar lordosis, thoracic kyphosis, head tilt) in healthy individuals.

👫 They included a total of 23 studies with 969 participants.

📊 Neither acute (d = 0.01, p = 0.97) nor chronic stretching (d=-0.19, p = 0.16) had an impact on posture.

📊 In contrast to stretching, chronic strengthening was associated with large improvements (d=-0.83, p = 0.01), but no study examined acute effects.

💪Strengthening was superior (d = 0.81, p = 0.004) to stretching.

📊 Subgroup-analyses found strengthening to be effective in the thoracic and cervical spine (d=-1.04, p = 0.005) but not in the lumbar and lumbopelvic region (d=-0.23, p = 0.25). Stretching was ineffective in all locations (p > 0.05).

💡 In conclusion, the common recommendation of stretching tight or shortened skeletal muscle to improve muscle imbalance and posture lacks scientific evidence (moderate certainty). In contrast, this review reinforces the role of strengthening weak antagonists which, however, was only effective in the thoracic and cervical but not in the lumbar spine (moderate certainty). The authors speculate that hypertrophy would be associated with a larger number of parallel titin-myosin filaments, which could lead to a higher tensile muscle stiffness.

Example exercises (https://www.mdpi.com/1660-4601/17/15/5430) (a) axial elongation exercise, (b) craniocervical flexion exercise, (c) craniocervical extension exercise, (d) rowing exercise, (e) Y exercise.

Pierre Frédy, baron de Coubertin, que l'on connaît surtout pour avoir donné un nouveau souffle aux Jeux olympiques, est avant tout un grand théoricien de l'éducation populaire. Le 25 novembre 1892, il annonce que, sur une base conforme aux conditions de la vie moderne, il pense au rétablissement des Jeux olympiques. Deux ans plus t**d, un congrès international réuni à Paris, vote à l'unanimité la constitution d'un Comité international olympique. Il est amené à le diriger entre 1896 et 1925.
