It works — just not for the reasons, or at the times, most people assume.
Stage by stage
- The hold (30 seconds or longer): Holds of roughly 30 seconds or more, repeated, are what produces measurable effects in research.
- Early weeks (Tolerance increases first): Your nervous system permits more range before triggering protective tension, while tissue stiffness changes little.
- Months later (Genuine structural change): With sustained practice, real adaptation occurs including changes to muscle fascicle length.
- Timing (Not immediately before training): Prolonged holds before training temporarily reduce force and power, so afterwards or in a separate session is better.
Muscles trained
- Primary: hamstrings, shoulders
- Secondary: lower back, calves
Intensity
2.3 METs (Stretching, mild).
Time to effect
- Wks–mo: Range improves within weeks; lasting structural change takes months.

Common myth
“Stretching prevents injuries and reduces muscle soreness.” In reality: Reviews find no meaningful injury-prevention effect and negligible effect on soreness — what it reliably does is improve range of motion.
