The Claim

Stretching before exercise prevents muscle soreness and injuries.

Verified by Lenz ·

The Short Version

This claim is not supported by the best available evidence. Multiple high-quality systematic reviews, including a 2022 Cochrane review, consistently find that stretching before exercise does not produce clinically meaningful reductions in muscle soreness (DOMS) and does not significantly reduce general injury risk. While some newer research suggests specific stretching types (e.g., individualized active stretching) may help in narrow contexts, these tentative findings do not support the broad, blanket claim as stated.

Caveats

  • The claim collapses important distinctions between static and dynamic stretching — evidence suggests they have very different effects, and static stretching before exercise may actually impair performance.
  • High-quality Cochrane and systematic review evidence consistently shows no clinically important reduction in delayed-onset muscle soreness (DOMS) from pre-exercise stretching.
  • The few supportive sources are either tentative and narrow in scope (limited to specific injury types or individualized programs) or come from clinic/marketing websites rather than controlled trials.
