Exercise guide

Cable Single Arm Crossover

  • Intermediate
  • Isolation
  • Rep-based
  • Chest

This isolation exercise targets the pectoral muscles, specifically emphasizing the inner chest and allowing for a greater range of motion by crossing the midline of the body. The unilateral nature helps address muscle imbalances and improves core stability through the trunk.

Equipment

  • Cable

Setup

  1. Set the cable pulley to shoulder height and attach a single D-handle.
  2. Stand sideways to the cable machine and grab the handle with your outside hand using a neutral grip.
  3. Take a small step away from the machine to create tension, and use your inside hand to hold the machine frame or a pull-up bar for stability.
  4. Position your feet in a staggered stance with your chest up and shoulders retracted.

How to do it

  1. With a slight bend in your elbow, pull the handle across your body toward your midline, exhaling as you contract the chest.
  2. Continue the movement until your hand crosses the center of your chest to achieve a peak contraction.
  3. Inhale as you slowly return the handle to the starting position, maintaining a slight bend in the elbow and constant tension on the muscle.
  4. Maintain a controlled 2-1-2 tempo, focusing on the stretch at the end of the eccentric phase.

Form checklist

  • Keep your torso stationary; avoid rotating your hips or shoulders to swing the weight.
  • Maintain a consistent, slight bend in the elbow throughout the entire range of motion.
  • Ensure your shoulder stays pinned back and down, rather than rounding forward at the end of the movement.
  • Keep your wrist firm and neutral to avoid unnecessary forearm strain.

Pro tips

  • Focus on bringing your bicep toward your sternum rather than just moving your hand to maximize pectoral shortening.
  • Pause for one second at the point of maximum contraction across the midline to enhance the mind-muscle connection.

Make it harder

  • Implement a 4-second eccentric (lowering) phase to increase time under tension.
  • Perform the exercise without holding onto the machine for stability to increase the demand on your core and obliques.
