Hack Squat Good Morning

The hack squat good morning is a hip hinge performed on the hack squat machine, with the shoulders under the pads and the torso folding forward instead of the knees bending. It loads the hamstrings, glutes and lower back through a controlled range, and the machine's fixed path supplies the stability that a barbell good morning asks the lifter to create alone. That support is the whole point: it lets you chase tension in the posterior chain without fighting for balance. Is it a replacement for the barbell version? No, it is a safer accessory. Because the sled travels on rails, most lifters can work in the ten to twelve rep range with a load they would never hinge under free-standing. Keep the back flat throughout, move slowly, and stop the set as soon as the spine starts to round.
