Lie prone on the pad of a T-Bar machine and grasp the handle with a neutral or pronated grip depending upon preference or programming.
Hinge forward until your torso is roughly parallel with the floor (or slightly above) and then begin the movement by driving the elbows behind the body while retracting the shoulder blades.
Pull the bar towards your body until the plates touch your chest and then slowly lower the handle back to the starting position under control.
