Lats vs Upper Back: How Elbow Flare and Scapular Motion Decide Which Muscle Works

If you only feel your traps and the back of your shoulders when you row, your elbows are probably flared and your shoulders are probably shrugging. That arm path favours the upper back. To shift the work toward the lats, keep the elbows closer to your ribs and drive them toward your hip.

This is the most common confusion in back training, and it is why the “lats vs upper back rows” question keeps coming up. It sits inside our complete guide to back training, and here we turn it into a rule you can check in about five seconds.

One honest warning first. The exact angles you see online (tucked under 30 degrees, flared 45 to 90) are coaching cues. I could not find a study that tested those specific numbers. What the research does support is the direction of the rule, and it is also clear that small tweaks change less than most gym lore claims.

What do the lats and the upper back actually do?

The lats run from your spine and pelvis up to the front of your upper arm. According to a 2026 review of EMG studies, they produce shoulder extension, adduction and internal rotation (Di Fonza et al., 2026). In plain terms: they pull your upper arm down and back toward your body.

The upper back muscles (mid traps, rhomboids, rear delts) do a different job. They pull the shoulder blade toward the spine and swing the arm out and back. Think of a reverse fly or a face pull.

So the question for any pull is simple. Is my upper arm travelling down and back toward my hip, or out and back toward the side? The first loads the lats. The second loads the upper back.

The same review notes that the humerus-to-trunk relationship may be a key determinant of how load is spread across muscles in pulling exercises (Di Fonza et al., 2026). That is the research version of the elbow rule.

Why do I feel traps instead of lats on rows?

Three habits cause it, usually together.

• Flared elbows. The upper arm points out to the side, so the work moves to the rear delts and mid back.
• Shrugging into the pull. Shoulders rise toward your ears before the elbows move.
• Pulling to the chest. A high finish point matches a flared arm path.

In the gym, this looks like a lifter on a seated cable row leaning back, hands finishing at the sternum, elbows wide, and a burn across the back of the shoulders. It is a legitimate upper-back row. It is just not a lat row.

The elbow path rule: tucked for lats, flared for upper back

Here is the rule, stated carefully.

• Lat-leaning: the elbow travels close to the ribs, roughly under 30 degrees away from your torso, and the handle finishes near the hip or lower ribs.
• Upper-back-leaning: the elbow travels wide, roughly 45 to 90 degrees from the torso, and the handle finishes at the upper chest or face.

What backs this up? The review linked above found that in the seated row, a lower shoulder-abduction angle (elbows closer to the body) was associated with greater lat EMG amplitude in one study, and a narrower grip in another (Di Fonza et al., 2026). The authors are explicit that those two variables have never been tested together and that EMG amplitude is not the same as long-term growth.

Even so, the direction makes sense anatomically and lines up with the research. Use it to choose, then check how your own back feels.

Does scapular retraction vs depression change anything?

Yes, but less than most people think.

Depression means the shoulder blades move down, away from your ears. Retraction means they move toward the spine. Lat-focused pulls tend to be taught with depression first (think pulling the shoulder blades into your back pockets), while upper-back rows are taught with retraction at the finish. For a deeper dive into the cue itself, see our guide on scapular retraction vs depression and the mind-muscle connection.

The studies are a bit humbling:

• A 2004 study compared seated rows with an actively retracted scapula and with non-retracted scapulae. Actively retracting did not change mid trap and rhomboid activity, though the seated row overall produced the highest activity in that muscle group (Lehman et al., 2004). Note it used isometric holds, not full reps.
• A 2025 study had 14 resistance-trained men perform seated rows with either a fixed or a free scapular position. Overall excitation was comparable. The fixed condition showed more posterior deltoid in the lifting phase, and more mid trap (ES 0.67) and lat (ES 0.85) activity on the return (eccentric) phase (Padovan et al., 2025). The authors conclude that scapular constraint changes how excitation is distributed more than how much there is.

The takeaway: scapular position fine-tunes the pull. Elbow path decides the broad emphasis.

Does grip width or handle choice matter?

Less than the internet suggests.

In a 2014 study, 15 men did 6-rep-max lat pulldowns with grips of one, one and a half and two times their shoulder width. Lat, trap and infraspinatus activity was similar across widths. They lifted slightly more with the narrow (80.3 kg) and medium (80 kg) grips than the wide grip (77.3 kg), and the authors concluded that similar muscle activation, and likely similar growth, can be expected across that range (Andersen et al., 2014).

A 2010 study of 12 men compared wide and narrow, pronated and supinated pulldown grips. The overhand (pronated) grip produced more lat activity than the underhand grip, regardless of width (Lusk et al., 2010). So “wide equals lats” is not well supported, while grip orientation might matter a little.

Where you pull the bar also counts. In a 2024 comparison, 14 trained men did pulldowns to the front of the face and behind the neck. The front version produced greater lat excitation as the bar came down and overall greater excitation in the prime movers, although the behind-the-neck version showed more lat activity as the bar went back up (Padovan et al., 2024). The 2026 review reaches a similar conclusion about the front path.

Practical translation: choose the handle that lets your elbows travel the way you want. If a straight bar pushes your elbows wide, try a neutral or V-handle. If you feel more lat with a close neutral grip, use it. For attachment specifics, see seated cable row attachments and elbow drive.

Do torso angle and range of motion change the target?

Somewhat, and results are mixed.

In a 2025 trial, 16 resistance-trained men did prone barbell rows through three ranges of motion at 10RM. Lat excitation was higher in the upper-half range than in the lower-half or full range (d around 0.6), and peak trapezius excitation was lower in the upper half. The authors call the overall effect medium at best and inconsistent, and conclude that range changes have limited impact on overall activation (Fischer et al., 2025).

Notice what that implies. Range of motion moves the numbers a little, and torso angle on its own has barely been tested. Keeping the trunk steady and moving the elbows consistently matters more than finding a magic angle.

For the chest-supported version, where the pad removes momentum and makes the upper back easier to feel, see our guide to chest-supported rows for upper back hypertrophy.

What about pull-ups, pulldowns and chin-ups?

Vertical pulls naturally keep the elbows in front of the torso and moving down, so they tend to look more lat-friendly.

A 2010 study of 25 people measured pull-up, chin-up and a rotating-handle variant. Lat activity was very high in all of them, with averages of 117 to 130% of a maximum isometric contraction, and no lat difference reported between the three. The chin-up produced more pectoralis major and biceps activity, while the lower trapezius was more active in the pull-up (Youdas et al., 2010).

That suggests vertical pulls are a dependable lat option, and that the lower traps also work to keep the shoulder blades down. For more on width and grip in the pulldown, see our article on wide vs close vs neutral grip lat pulldowns.

How to audit any back exercise in 5 seconds

Ask three questions.

1. Where does the elbow point? Close to the ribs leans lat. Out wide leans upper back.
2. Where does the handle end? Hip or lower ribs leans lat. Upper chest or face leans upper back.
3. What do the shoulder blades do? Down, then back leans lat. Pinched together leans upper back.

Quick examples:

• Neutral-grip seated row, elbows brushing your ribs, handle to the belly button: lat-leaning.
• Rope or wide bar row, elbows out, pull to the sternum: upper-back-leaning.
• Reverse pec dec: almost entirely upper back and rear delts.
• Close-grip lat pulldown to the upper chest: lat-leaning, with the biceps helping.

A practical way to use this in a back day

You do not need to pick a side. Use both styles on purpose.

• First lift (fresh): a lat-biased movement, such as a pulldown or tucked-elbow row, for 2-3 hard sets.
• Second lift: an upper-back row with flared elbows or a chest-supported row, for 2-3 hard sets.
• Finisher: a reverse fly or similar rear-delt movement if you want extra upper-back work.

Our pull day plan puts this kind of split into a complete session. And if you want the wider picture on choosing exercises by what they actually load, the exercise selection and biomechanics guide covers the logic. For the cue that helps you feel the lats working, see lat flare and mind-muscle connection cues.

When to see someone about it

If a flared or heavy row causes sharp pain at the front of the shoulder, tingling down the arm, or pain that lingers after training, stop that variation and speak to a doctor or physiotherapist. Do not try to diagnose it from an article, including this one.

Limits of the evidence

Most of the studies above are small, short, and used healthy young men. EMG amplitude shows how active a muscle is during a set, not how much it grows after months of training. The elbow-angle numbers in this article come from coaching practice, not a controlled trial. Treat them as a way to organise your thinking, and let your own feel and progress over a few weeks confirm what works for you.
