This is a hip abduction Reactive Neuromuscular Training exercise.

SPLIT STANCE HIP HINGE
Begin from a split stance position.

Transfer the majority of your weight onto the front foot (80/20). The back leg should only be lightly touching the ground.

With a slight bend in the front knee, slowly hinge from the hips pelvis and upper body inwards towards your supporting leg and wall.

It is important to make sure that your hips are stable and all the movement is coming from a hinging motion.

You should feel tension in your hamstring and glute of your working leg, but not in your quad.

Using the supporting leg and pelvis push away from the wall to original position.
Repeat for desired reps.
