The Nordic hamstring exercise preferentially recruits the semitendinosus muscle rather than the biceps femoris long head.
Include Nordic hamstring curls in your routine for overall hamstring strength and injury prevention, but understand they primarily target the semitendinosus. To ensure balanced hamstring health, combine them with hip-extension exercises like the 45° hip extension to target the biceps femoris long head.
GoodSupportsHIGH confidence
the Nordic exercise preferentially recruits the semitendinosus.
Why this rating
Confirmed by both sEMG ratios and fMRI T2 changes with high statistical significance.
