Resistance Band Single Arm Row: A Complete Guide
Also called Band One Arm Row, Banded Single Arm Row
Quick Intro
Resistance Band Single Arm Row, also called the Band One Arm Row or Banded Single Arm Row, is a strength exercise performed by anchoring a resistance band low, standing in a staggered stance, holding the band in one hand and rowing the elbow back while bracing the core to resist rotation. It trains one side of the back at a time, using the same low anchor as a bilateral row but with the whole trunk now working to keep the body from twisting toward the pulling arm.
Equipment Needed
Resistance Band Single Arm Row needs a resistance band, the only required equipment, anchored to a low, sturdy point.
Why Resistance Band Single Arm Row Matters
Pulling the elbow back is driven mainly by the upper back: the wide back muscle running from the spine to the arm (latissimus dorsi) drives most of the pull, while the muscles between the shoulder blades (rhomboids) and the upper back (trapezius) draw the shoulder blade back as the elbow passes the ribs. A muscle near the armpit (teres major) assists the lat in the same pulling action, and the rear shoulder (deltoid, posterior) helps finish it. The front of the upper arm (biceps brachii and brachialis) bends the elbow to help draw the band in. Because only one arm is pulling, the side of the torso (obliques) and the deep core (transverse abdominis) have work to do too, bracing against the band’s pull to keep the trunk from rotating toward the working side. Muscular endurance is the defining demand of this exercise, the same continuous-tension signature every banded pull carries, since the band never lets the pulling arm rest the way a dumbbell nearly does near the top of a similar row.
When to Do It
Resistance Band Single Arm Row fits naturally into an upper body or pulling-focused session, often used as accessory work after a heavier bilateral pull to give a weaker side its own full effort. Twice a week on each side, with a rest day between sessions targeting the same muscles, is a reasonable working frequency.
A known strength imbalance between the left and right side is a reasonable signal to prioritize this exercise, since training one arm at a time is what closes that kind of gap. Anyone with a shoulder that’s currently irritated should still keep the band light regardless, since a single-arm pull loads that joint just as directly as a bilateral one does.
Getting Ready
Securing the anchor point at a low, sturdy mount comes first, since a loose anchor undermines the whole set before the first rep even happens. Standing in a staggered stance, the leg opposite the working arm forward, gives a stable base to brace against the band’s pull.
Rehearsing the pull on the weaker side first, while the torso is freshest, gives that side the best shot at clean reps before any fatigue sets in. A couple of slow, exploratory pulls on each arm confirm the anchor holds steady and the band’s tension feels right before the working set begins.
Step-by-Step Instructions
1. The anchor and stance. Secure the band at a low, sturdy point and stand in a staggered stance, the leg opposite the working hand forward.
2. The setup. Grasp the band in one hand with the arm extended toward the anchor, torso upright and braced against rotation.
3. The pull. Drive the elbow back past the ribs, keeping the torso still and square while the shoulder blade draws back.
4. The release. Extend the arm back toward the anchor under control, then complete all reps on one side before switching.
How Many, How Often
Resistance Band Single Arm Row is dosed per arm, since each side works independently and a strength difference between them is common and worth training around.
| Level | Where you’re at | What to do |
|---|---|---|
| Beginner | New to unilateral banded pulling | 3 sets of 10 to 12 reps per arm with a band light enough to keep the torso completely still. |
| Intermediate | The torso stays square through a full set | 3 to 4 sets of 10 to 12 reps per arm with a band where the last 2 to 3 reps are hard to finish without rotating. |
| Advanced | Comfortable finishing a set with no visible rotation | 4 sets of 8 to 10 reps per arm, or add a brief pause at full contraction to increase time under tension without changing the band. |
A torso that stays completely still and square through the whole set matters more here than the band’s resistance level, since rotating to help the pull along quietly shifts tension off the back muscles this exercise is meant to train.
Modifications and Variations
Resistance Band Single Arm Row sits between an easier, bilateral entry point and a harder, rotational progression.
For an easier entry point, Resistance Band Row uses both arms together on the same low anchor, removing the anti-rotation demand entirely since two arms pulling together keep the torso naturally balanced.
For more difficulty, Resistance Band Rotational Row adds a deliberate trunk rotation into the pull itself, a more advanced version that turns the anti-rotation bracing this exercise asks for into an active rotational movement instead.
Move to the single arm version once a bilateral row feels completely controlled, and move to the rotational version only once a strict, non-rotating single arm pull is solid on both sides.
Common Mistakes to Avoid
Rotating the torso toward the working arm. Letting the trunk twist as the pull comes in uses the body’s own rotation to help move the band, taking anti-rotation work away from the core. Keeping the torso square and still through the whole pull is the entire point of doing this one arm at a time.
Letting the elbow flare out to the side. Pulling the elbow away from the body shifts emphasis onto the rear shoulder instead of the lats. Keeping the elbow tracking back close to the ribs keeps the lats doing the work.
Training the stronger side for more reps. Stopping both arms at the same rep count lets a naturally stronger side quietly do less work relative to its capacity. Giving each arm its own full, challenging set closes a strength gap instead of preserving it.
Skipping the staggered stance. Standing with both feet square removes some of the base needed to resist the band’s rotational pull. A staggered stance, the opposite-side leg forward, gives a stable base to brace against.
After Your Set
A standing side bend, reaching the working arm overhead and leaning gently away, stretches the side of the torso that spent the set resisting rotation. Rolling the shoulders through a few slow full circles loosens the rear shoulder and upper back on the side that just finished pulling.
Going Deeper
Progress on Resistance Band Single Arm Row often gets judged by how heavy a band the stronger arm can pull, but the test is whether the weaker side can match it without the torso bailing it out through rotation. A side that only completes its reps by twisting toward the band hasn’t closed the gap, it’s just found a different way to hide it.
Someone comfortable with a controlled bilateral row already typically holds a strict, non-rotating single arm pull through 10 to 12 reps on both sides within the first two to three weeks, and closes a noticeable side-to-side strength gap somewhere in the six to eight week range.
How to Know You’re Improving
- A torso that stays square and still through a full set on both sides
- A full pull that reaches the ribs with the shoulder blade drawn back on every rep
- A band and rep count that feel close to even between the left and right arm
- A controlled release back to the starting stretch, not a fast, uncontrolled snap back
A torso that stays still on the weaker side, not just the stronger one, is what progress looks like here.
Muscles Worked
- Latissimus Dorsi (a large back muscle, pulling one arm back against increasing band tension)
- Rhomboids (the muscles between the shoulder blades, retracting the blade on the working side)
- Trapezius (a muscle across the upper back and neck, keeping that shoulder down through the pull)
- Teres Major (a small muscle under the shoulder blade, drawing the upper arm back past the ribs)
- Posterior Deltoid (the back of the shoulder, taking the arm behind the body at the finish)
- Biceps Brachii (the front of the upper arm, bending the single working elbow)
- Brachialis (a muscle under the biceps, supporting that elbow through the whole range)
- Obliques (the muscles along the sides of the abdomen, resisting the twist a one-armed pull applies)
- Transverse Abdominis (a deep core muscle that wraps around the torso like a corset, holding the torso square to the anchor)
FAQ
What’s the difference between this and the regular Resistance Band Row? Resistance Band Row uses both arms on the same anchor at once, which keeps the torso naturally balanced. This version pulls with one arm at a time, adding an anti-rotation demand the bilateral version doesn’t have.
Why does my weaker arm want to twist my torso during the pull? That’s the body finding an easier path when the target muscles aren’t yet strong enough to finish the pull on their own. Using a lighter band on that side until the torso can stay still is a reasonable short-term fix.
Should both arms use the same band? Not necessarily. A strength difference between sides is common, and using a slightly lighter band on the weaker side while it catches up is a reasonable approach.
Can this be done seated instead of standing? A seated version removes the staggered stance and most of the anti-rotation demand, which changes what the exercise is training. The standing staggered stance is what makes this version distinct.
