Attach belt on low pulley cable by attaching carabiner on belt buckle. Grasp attached belt, face away from pulley, and place head in belt loop. With belt above ears, clamp belt snugly around head by tightly gripping ends close to back of mid-head. With neck braced and assistance of arm, lunge forward to angle torso forward with feet staggered. Place hand on lower thigh for support.
Pull head forward and down by flexing neck until chin touches upper chest. Return by hyperextending neck until head is angled upward. Repeat.
Use neck to pull belt rather than allowing hand to assist. Keep clinched grip on belt against back of mid-head throughout movement. Clamping belt higher up further from base of skull will permit torque throughout fuller range of motion, particularly range of motion nearer full flexion.
Woven cotton or cloth belts tend to slip less from forehead. If belt slips from head, place small towel between belt and head. Cable carabiner slips to one side on square buckles and stresses belts structural integrity under heavy loads. Rounded buckle is more ideal since it provides more even stress on belt. Belts not made specifically for weight training may cause injury if they fail under load in which they were not designed.
Exercise can also be performed off of rack with belt, nylon rope, and plate holder from wrist roller. Nylon rope offers less friction on smooth rounded fixed surface. Alternatively, non-nylon ropes can be used off of revolving barbell sleeve on smith machine. See Cable Neck Flexion with belt and rope
