We are big on doing exercises that mimic the movement or activity we are trying to retrain as closely as possible.
The hamstrings need to eccentrically lengthen during the end of the swing phase and then concentrically activate as the leg drives towards the ground at initial contact and then through the full stance phase of gait.
Often this gets trained through some sort of lunge or step up which certainly has its value. However that is a closed chain exercise and that is not what happens in real life.
The eccentric to concentric transition of the hamstring happens in the open chain with no feedback from the ground.
This transition is also when a lot of hamstring strains occur. Is that a coincidence with training or is it a cause? We will probably never know for sure, there are too many variables.
But it brings me back to retraining the movement as closely as possible to the movement or pattern that is problematic.
I love this exercise variation. One reason is the ability to move the hamstrings under tension, in a controlled manner with way more velocity possible than a box step up or lunge. Another is that it is open chain and your brain needs to be able to have awareness of your limbs in space, without the ground as a feedback point.
