The single-arm cable cross-over is an isolation movement that uses a cable stack to build bigger and stronger pectoral muscles. Working the chest one side at a time allows you to focus on the 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.
Unlike dumbbells, cables provide constant tension, including at peak contraction
Can quickly switch weights for dropsets
Stretches the chest muscles under load which can lead to greater muscle gain
Begin by moving the pulleys to the high position, select the resistance to be used, and take a handle in each hand.
Step forward in front of both pulleys with your arms extended in front of you, bringing your hands together. Your head and chest should be up as you lean forward, while your feet should be staggered. This will be your starting position.
Keeping your left arm in place, allow your right arm to extend out to the side, maintaining a slight bend at the elbow. The right arm should be perpendicular to the body at approximately shoulder level.
Return your arm back to the starting position by pulling your hand back to the midline of the body.
Hold for a second at the starting position and repeat the movement on the opposite side. Continue alternating back and forth for the prescribed number of repetitions.
