BARBELL GOOD MORNINGS
The fundamental movement here is the hinge (push glutes back, keep weight in heels, knees stay over ankles and torso lowers to become parallel with the ground). This could be compared to a Romanian dead lift or stiff leg dead lift. The primary difference here is where the weight is located. Since the barbell is resting on top of the upper trap muscles, we are required to maintain a much stronger core than if the weight were to be hanging from our arms as in a dead lift.
