Research Findings

Evidence-backed insights

A 2024 meta-analysis of 89 stretching studies found that static stretching held for >60 seconds before training reduced strength output by 5.8% and power output by 4.2%. Dynamic stretching before training improved performance by 3.1%. PNF stretching produced flexibility gains 15-20% greater than static stretching alone.
