Primary muscles worked are the glut and lower back.

Use the ankle belt attached to the low split weight pulley. Connect the ankle belt around your ankle.

Position your self so you are facing towards the machine and approximately one arm length from the machine. Lean slightly forward and stabilize your self by holding on to the legs of the bench unit. Keep your foot close to the lower pulley and bend your knee slightly in the start position. Lift the weight by driving your leg back until you reach full contraction in your glut muscle. Lower the weight under control. Repeat with your other leg when you have finished your reps.
