One thing you want to keep in mind – is to maintain a straight back throughout the exercise all the way to the ground. When the hamstrings start to fatigue – the trunk will tend to flex forward.

If this is too difficult – you can do assisted curls by holding an exercise band over the shoulders (secured behind and above you) or a weighted cable at the gym to reduce the forward load.

Clinical Application & Conclusions:

The evidence indicates that overall, the NHE is effective in preventing hamstring injuries – reducing the risk by approximately 50%! The authors concede that the mechanisms by which NHE provides its protective effect are not yet fully understood, however. Other authors have noted increased eccentric strength and suspect that it may be responsible for the positive effect (9), although the evidence is minimal, due to the poor incorporation of NHE into regular training programs. As such, there is a need for improved understanding of the factors relating to the incorporation of the program into training and the mechanisms responsible for its effect.
