What this means in real training
Why the claim sounds convincing
Common recovery action with a straightforward meaningful-effect question.
The mistake is turning a possible mechanism, average association, or useful option into a universal rule.
What the evidence supports
Stretching may feel good, but it does not reliably prevent meaningful delayed muscle soreness. The relevant evidence needs to match the exact population, intervention, comparison, and real-world outcome instead of borrowing certainty from a mechanism, acute response, or marketing label.
How large is any soreness effect, and should flexibility work be justified separately?
Mechanisms, short-term measurements, and anecdotes can explain interest, but they do not automatically establish long-term benefit or safety.
The useful verdict depends on dose, training status, baseline habits, adherence, and whether the measured outcome matches the promise.
How to use the answer
Stretch for mobility or preference, and manage soreness mainly through sensible progression, recovery, and time.
Study populations, protocols, outcome definitions, and follow-up periods vary.
Averages do not guarantee the same response for an individual reader.
Pain, illness, pregnancy, medication use, or medical exercise restrictions can change the practical decision.
