Stand facing behind cable bar mounted on each side to shoulder height narrow double pulley cables. Grasp cable bar with wide overhand grip. Position bar chest height with elbows angled behind and above. Lean and step forward with one foot in front, bending forward knee.
Push cable bar forward and downward until bar is about hip height and arms are straight. Return cable bar to original position until slight stretch is felt in chest or shoulders. Repeat.
Cable pulleys should be relatively close together, narrower than width of arms extended out to sides (but not too close), closer than what is typically found on standard cable cross over setup.
