You’ve seen the guy at the gym. He’s loaded up the seated row machine with every plate in the building, bracing his feet like he’s trying to kick down a door, and yanking the handle toward his stomach with a violent, whole-body seizure. It looks impressive. It’s also kinda useless if the goal is actually growing a thick, detailed back. If you want to stop guessing and start feeling your lats actually work, you need to stop pulling with both hands and embrace the single arm seated row.
Most of us have a dominant side. It’s natural. You carry groceries with your right hand or reach for the high shelf with your left. Over years of training, those tiny preferences turn into massive strength imbalances. When you use a standard double-handle bar, your strong side takes over about 60-70% of the work. You don't even notice it's happening. By switching to a unilateral (one-arm) movement, you force each side to stand on its own. No hiding. No cheating.
The Biomechanics of Why One Arm is Better Than Two
There is a specific reason why the single arm seated row feels "deeper" than the standard version. It’s about the ribcage. When you pull with both arms, your torso stays squared up. This limits how far back your elbow can travel because the scapula (your shoulder blade) eventually hits a wall against your spine.
But when you go one arm at a time? Everything changes. You can slightly rotate your torso into the movement. This isn't "cheating" rotation; it’s anatomical alignment. By allowing a small amount of natural rotation at the end of the pull, you can get the elbow further back, which leads to a more intense contraction of the latissimus dorsi and the lower traps.
According to Dr. Stuart McGill, a leading expert in spine mechanics, unilateral loading also fires up the core in a way bilateral movements can't touch. Your obliques have to fight to keep you from spinning off the bench. So, while you're technically "doing back," you're actually building a trunk that’s solid as a rock. It's basically a sneaky way to get an ab workout while you chase a V-taper.
Getting the Setup Right (Because Most People Don't)
Forget the long straight bar. You need a single D-handle. Attach it to the cable row machine and sit down. But here is the trick: don't sit square.

If you are rowing with your right hand, try shifting your right butt cheek slightly back on the seat or even placing your left foot forward on the floor rather than on the footplate. This "staggered" stance opens up the hip and gives your lat a direct line of pull. It feels weird at first. Then you do a rep and realize your back has never felt this tight. Honestly, the first time I tried this, it was a total lightbulb moment.
Reach forward. Let the weight stretch your shoulder blade out. You want to feel that "pull" under your armpit. That's the lat stretching. If you don't feel the stretch, you're just doing a heavy bicep curl. Pull the handle back by driving your elbow toward your hip—not your ribs. Think "elbow to pocket." This cue is the difference between a massive back and just having sore forearms.
Why Your Lat Shoulders All the Blame
People complain about "not feeling" their back. Usually, it’s because their traps and biceps are overactive. The single arm seated row fixes this by allowing a neutral grip (palm facing in).
When your palm faces down (overhand), your upper traps and rear delts want to do the heavy lifting. When your palm faces in, the line of force aligns much better with the fibers of the lower and mid-lat.

- The Stretch: Let the cable pull your arm forward until your shoulder blade "protracts" (slides away from the spine).
- The Initiation: Don't yank. Start the move by depressing your shoulder blade—think about tucking it into your back pocket.
- The Finish: Stop when your elbow is in line with your torso. Pulling it way past your body usually just tips the shoulder forward (anterior tilt), which can lead to impingement issues over time.
It’s about tension, not distance. If you lose the "squeeze" to get the handle two inches further back, you've lost the set.
Addressing the "Functional" Argument
Let's talk about the term "functional training." It’s a buzzword that usually means nothing, but in the context of the single arm seated row, it actually applies. Real life happens one side at a time. Whether you're pulling a lawnmower cord or opening a heavy door, you're rarely perfectly symmetrical.
Studies in journals like the Journal of Strength and Conditioning Research have shown that unilateral training can actually increase strength on the opposite side of the body through a phenomenon called "cross-education." Basically, by training your right side intensely, your brain sends neural signals that help keep the left side from atrophying. It's wild science, but it works.
Common Blunders to Avoid
- The "Lawnmower" Yank: Don't use your legs to jump-start the weight. If you have to lean back 45 degrees to get the weight moving, it's too heavy. Drop the stack. Be humble.
- The Death Grip: Squeezing the handle like you’re trying to crush a soda can will fry your forearms. Try using a "hook" grip with your fingers and keep your thumb on the same side as your fingers. This relaxes the bicep.
- The Shrug: If your shoulder is touching your ear during the row, you're just training your traps. Keep your neck long.
Variations for the Bored or the Bold
If the standard cable version is getting stale, try the Half-Kneeling Single Arm Row. Get off the bench and put one knee on the floor. This removes the ability to "leg drive" the weight entirely. It's brutal. It forces your core to work overtime because you no longer have the footplates to brace against.
Another killer is the Single Arm Row with a Pause. Pull the weight back, hold it for a full three seconds at the peak contraction, and then take four seconds to let it back out. You won't be able to use much weight. Your lats will feel like they're on fire. That’s the goal.
Integrating This into Your Split
Don't replace your heavy pulls entirely. You still need some heavy barbell rows or weighted pull-ups to build raw mass. Think of the single arm seated row as your "precision tool."
It belongs in the middle of your workout. After you’ve done your big, taxing compound lifts, use this to isolate the muscles and fix the imbalances those big lifts might be masking. High reps are usually better here. Aim for 10-15 reps per side. Focus on the mind-muscle connection. If you're just moving the weight from point A to point B, you're wasting time.
Actionable Steps for Your Next Session
- Swap the attachment: Get rid of the V-bar or the Lat bar. Use a single handle.
- Film a set: Record yourself from the side. Is your torso staying relatively upright, or are you swinging like a pendulum? If you're swinging, drop the weight by 20%.
- Lead with the elbow: Imagine there is a string attached to your elbow and someone is pulling it from behind you. Your hand is just a hook.
- Work your weak side first: If your left arm is weaker, start with the left. Match the number of reps with your right arm. Never let the strong side dictate the volume, or the gap will just keep getting wider.
- Slow down the negative: The way back is where the muscle grows. Don't let the stack just slam back down. Control it.
