Hey Justin,

The banded lock outs in hip flexion and Nordic curl are both great but have different purposes. The banded hamstring lock out is about working on restoring your positions and exposure to end ranges while the Nordic curl is an exercise to build eccentric strength in the hamstring. The Nordic curl has grown in popularity as of late spurred on by a whole host of studies that have shown they are great for hamstring hypertrophy, increasing eccentric strength, improving sprinting, and reducing injury for athletes. So can be a benefit to anyone who runs fast or wants to do some hypertrophy work on their hamstrings.

Cheers,
Mike
