The single-arm incline cable cross-over is an isolation movement that uses a cable stack and a bench to target the upper part of the pectoral muscles. Working the chest one side at a time allows you to focus on balance between the sides of your chest and really feel the chest muscles contracting. It is common in upper-body and chest-focused muscle-building workouts, often in combination with other presses or flyes to target the chest from different angles.
