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.

Setup
- Set the cable pulley to shoulder height and attach a single D-handle.
- Stand sideways to the cable machine and grab the handle with your outside hand using a neutral grip.
- 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.
- Position your feet in a staggered stance with your chest up and shoulders retracted.
How to do it
- With a slight bend in your elbow, pull the handle across your body toward your midline, exhaling as you contract the chest.
- Continue the movement until your hand crosses the center of your chest to achieve a peak contraction.
- Inhale as you slowly return the handle to the starting position, maintaining a slight bend in the elbow and constant tension on the muscle.
- 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.
