Single-Arm Cable Row: How to Row One Side at a Time
One arm, one handle, and a few extra inches at both ends of the rep — the row that stops your strong side from quietly carrying your weak side.

What is the Single-Arm Cable Row?
The single-arm cable row is a seated or half-kneeling horizontal pull performed one side at a time against a low cable pulley. It trains the lats and rhomboids through a longer range than a two-handed row, because the free shoulder can travel forward into a stretch and all the way back into full retraction.
The one cue that matters: Row one arm at a time and resist letting your shoulder roll forward on the stretch.
Why the Single-Arm Cable Row is worth doing
- Lets the working shoulder blade slide further forward than a bar or a two-handed handle allows
- Exposes a side-to-side gap the moment one arm runs out of reps before the other
- Holds tension at the fully shortened position, where a free weight goes almost weightless
- Rows heavy without a hinged torso holding the load, because your ribcage is braced and static
How to do the Single-Arm Cable Row
- Set the pulley Clip a single D-handle to the lowest setting on the stack and sit facing it on the floor or a low bench, or drop into a half-kneeling stance with the outside knee down. The cable should run in line with the working arm, not across your body.
- Take the stretch Reach the handle forward and let the shoulder blade slide toward the pulley until the lat lengthens. The shoulder travels; the torso does not rotate to chase it.
- Drive the elbow back Pull until the handle reaches the lower edge of your ribcage and hold a full count with the blade pinned toward your spine. Elbow close to the ribs biases the lat, a wider path shifts it to the rhomboids — pick one and keep it all set.
- Return long Let the handle draw your arm forward over two to three seconds and allow the blade to protract at the very end. Stop the return the instant your torso starts turning toward the stack.
- End it square Row both sides for the number your weaker arm managed, then walk the stack down under control instead of letting it slam home.
Muscles worked
Because you drive the elbow down and back past the ribs, the Lats (latissimus dorsi) do most of the work — they extend and adduct the upper arm, and the single-arm setup lets the humerus travel further behind the torso than a fixed bar permits.
The Rhomboids (rhomboid major and minor) own the last two inches. With one hand free, nothing stops the shoulder blade sliding all the way to the spine, so the pause at the ribs is genuine retraction rather than a bar bumping your stomach.
BackMaxx files this under Upper Back with Lat Width and Symmetry as secondary zones, and the unilateral setup is why Symmetry is on that list. Each side gets its own rep count, range and failure point, which is the whole argument for unilateral work in a back symmetry block.

Form tips
- Pulley height. Set the cable at or just below hip height once you are seated. A high pulley turns the finish into a chest-height pull and takes the lat out of the bottom half of the range.
- A job for the free hand. Plant the non-working hand on the bench, your own knee or the seat pad. A hand hanging loose lets the torso counter-rotate on every rep and steals range from the side you are training.
- Blade moves, ribs do not. Protraction and retraction of the shoulder blade is the range you came for. Rotation of the ribcage is not, and it feels identical from the inside — film a set to check.
- The weaker side’s number. Row the weaker arm first and match it exactly on the strong side. Every extra rep on the strong side widens the gap you picked this exercise to close.
Common mistakes
- Rowing with the torso
- Leaning back on the pull and forward on the return turns twelve rows into twelve sit-ups and hides how far the lat moved. Stack the ribcage over the hips and let only the arm and blade travel.
- Cutting the reach short
- Ending the return when the elbow straightens, before the blade slides forward, deletes the one thing this row offers over a two-handed version. Add an inch of reach to every rep.
- Grip failing before the lat
- If the forearm quits at rep eight of twelve, the handle is the limit rather than the back. Drop a plate or use a strap and finish the prescribed range.
Sets, reps and where it fits
BackMaxx runs this at 3 sets of 10–12 per side, and it earns its place second or third in a back session — after a heavy two-handed pull, when the load is lower and the range matters more than the number on the stack. Leading with it is not wrong, but you will be rowing weights you could beat using both arms.
Progress by adding a rep to the weaker side until it owns 12, then move the pin one notch and restart at 10 on both. Ten to fifteen works if you want more time in the stretch; below eight the pause disappears and you have built a worse dumbbell row. It fits the Thickness Block, where horizontal pulls lead every session.
No cable? Do this instead
The closest match is the One-Arm Dumbbell Row — same single-side brace, same elbow path along the ribs. The difference is the top: a dumbbell goes nearly weightless where the cable stays loaded, so hold a hard one-second squeeze at your ribs on every rep to replace what the stack was doing for you.
Variations and similar exercises
- Seated Cable Row
- The two-handed version on the same stack, which loads far more weight but ends the pull when the handle hits your stomach — use it as the heavy anchor and keep single-arm work behind it.
- Meadows Row
- A one-side landmine row from a staggered stance, where the load rises as you pull instead of staying flat — for lifters who want a heavier top end from the same pattern.
- Chest Supported Row
- Trades all the anti-rotation work for a pad, so the back fails before the bracing does — pick it on days when holding your torso still is what limits the reps.
Frequently asked questions
Is the single-arm cable row better than the seated cable row?
Neither replaces the other. The seated row carries more load because both arms share it, so it drives the bulk of your Upper Back volume. The single-arm version gives more range and forces each side to earn its own reps. Run the two-handed row heavy first and the single-arm row for reps afterward.
Should I do single-arm cable rows seated or half-kneeling?
Seated on the floor or a low bench gives the longest range, because your hips are locked and the shoulder can reach a long way forward. Half-kneeling is the fix when nothing lets you sit close to the stack — it costs a little range but adds a forward leg to brace against.
Why does my shoulder roll forward at the bottom of the rep?
That roll is the shoulder collapsing rather than the blade protracting, and it usually means the weight is too heavy for the reach. Keep the chest tall, let the shoulder blade slide forward around the ribcage, and stop the return the moment the shoulder starts dropping toward the floor.
Should the Single-Arm Cable Row be in your plan?
BackMaxx scores your upper back from one photo and builds the week around whatever is lagging — so the Single-Arm Cable Row only shows up when it is the right call.
