Hamstring strains are common in any sprint sport. Programmes with Nordics have cut them by up to half.

  • van Dyk et al., 2019 · Meta-analysis: Programmes that included Nordic curls reduced hamstring injuries by up to 51%. (A later reappraisal judged the effect less certain because of study selection.)
