Single-Arm Cable Crossover
This exercise uses a cable machine to work one side of your chest at a time, pulling a handle from shoulder height across the front of your body. Working one arm at a time forces your core and stabilizing muscles to stay active throughout the movement. It's a good choice if you want to even out strength differences between your left and right sides, or if you're easing back into chest work after a long break.

Form cues
- 01
Set the pulley to shoulder height and choose a light weight to start — you can always add more.
- 02
Stand with one foot slightly in front of the other, like a relaxed walking stance, to give yourself a stable base.
- 03
Hold the handle with a light grip — your fingers, not a white-knuckle squeeze.
- 04
Keep a soft bend in your elbow throughout; your arm should never lock out straight.
- 05
Let your working arm swing out to the side only until it's level with your shoulder — stop there.
- 06
Pull the handle back to the center of your body in a smooth arc, as if you're hugging a large barrel.
- 07
Squeeze your stomach muscles gently as you pull — imagine someone is about to lightly poke your belly.
- 08
Pause for a full second at the center before switching arms — don't rush the transition.
- 09
Keep your chest up and your shoulders down, away from your ears, the entire time.

Common mistakes
Using too much weight — if your whole torso twists or jerks to complete the pull, the weight is too heavy; drop it until you can move smoothly.
Locking the elbow straight — a fully extended arm puts stress on the joint; keep a noticeable soft bend throughout the movement.
Letting the shoulder creep up toward the ear — if your neck looks scrunched in a mirror, consciously drop that shoulder before each rep.
Swinging the arm too far back behind the body — the arm should stop when it's in line with your shoulder, not behind it, to protect the shoulder joint.
Rushing through reps without pausing at center — skipping the pause removes the benefit of the squeeze; slow down and hold for one count.
Scale it
Easier and harder variations
Easier
Use the lowest resistance pin on the stack and focus entirely on the motion before adding any real load.
Use this when learning the movement pattern or returning after time away from exercise.
Harder
Add a half-second pause at the fully extended position before pulling back, increasing the time your muscles are under tension.
Use this once the standard version feels controlled and easy for all sets.
Note
If you have shoulder discomfort, reduce the range of motion — only let your arm travel out to 45 degrees rather than full shoulder height, and stop immediately if you feel pinching.
Use this with a shoulder impingement, rotator cuff issue, or recent shoulder surgery, and clear it with your doctor or physical therapist first.
