Cable Crossover
The cable crossover is a great isolation exercise for the chest and anterior shoulder muscles. Cable crossovers are often paired with bench presses to achieve additional definition and growth (hypertrophy) in the chest muscles. You may adjust the height of the pulleys to change the angle of the resistance.
