Rhomboid exercises: which rows and pulls the studies measured, and what they didn't

The rhomboids are two thin muscles between your spine and your shoulder blades, under the trapezius. They pull the shoulder blades back toward the spine. Because they are deep, they are harder to measure than the surface muscles next to them, so this page is short on certainty and says so.

It is about training. I'm not making any promise here about posture or pain; if you have pain between your shoulder blades or in your neck, that's a question for a doctor or a physical therapist. I'm a fitness coach, not a doctor.

What was measured

A few studies put a thin wire electrode into the rhomboid major, which measures it on its own. All were small and in healthy adults, mostly men, and they measured activity during a single session, not growth over weeks:

• Row-type pulls. In 15 men doing 12 rubber-tubing exercises, seven of them, including low scapular rows, produced moderate activity, above 20% of a maximal contraction, in every muscle tested, rhomboid major included.¹ In 23 men, the study's lawnmower and robbery exercises produced more rhomboid major activity than its inferior glide and low row.²
• Arms overhead. In 26 people comparing a shrug with the arms at the sides, a shrug overhead and a retraction with the arms overhead, rhomboid major activity was significantly higher in the retraction and lower in the overhead shrug.³
• Face-down and side-lying arm moves. In 26 healthy people, rhomboid major activity was moderate, 25 to 45% of a maximal contraction, in four shoulder exercises: side-lying external rotation, side-lying forward flexion, prone horizontal abduction with external rotation and prone extension.⁴ In 16 men doing five multijoint exercises, it ranged from 34.6 to 54.2% and did not differ between them.⁵

Studies that used surface electrodes report the middle trapezius and the rhomboids as one group, but they give one more row result: in 12 men holding each pull still, the middle trapezius and rhomboid group was most active in the seated row of the four pulls tested, and actively pulling the shoulder blades back made no difference to it.⁶ And in 25 healthy adults, suspension push-ups produced more middle trapezius and rhomboid activity than floor push-ups.⁷

Which exercises on this site that covers

So the honest summary is that rows have the most support, the arm-back moves have some, and the rest of the list is a reasonable guess from how the movement looks.

A rhomboid session (practical)

This is a practical layout, not a protocol from a study. Pair it with a vertical pull on your back day: the lat exercises are the other half.

1. A row. Seated cable row or dumbbell row, three sets of 8 to 12. Pull your elbow back, not your hand up.
2. A second row or a reverse fly. Inverted row, or a face-down reverse fly with a light dumbbell, two or three sets of 10 to 15.
3. An arm-back finisher. Face pull or band pull-apart, two sets of 12 to 20.

Stop each set with a rep or two left. (How to judge reps left.) The 2026 American College of Sports Medicine stand found muscle growth was enhanced by ten or more sets per muscle group a week,⁸ and that figure is for a whole muscle group, not for the rhomboids alone, so count your row sets toward your back total. At home, a band anchored at waist height does the row, the reverse fly and the pull-apart.

Common questions

Do rows work the rhomboids?

In the studies cited here, yes: row-type pulls with a band produced moderate activity in the rhomboid major,¹ and the seated row produced the most activity in the middle trapezius and rhomboid group of the four pulls tested.⁶

Should I squeeze my shoulder blades together on rows?

Either way worked in the measurement. Actively pulling the shoulder blades back made no difference to middle trapezius and rhomboid activity in the 12-man study.⁶ Pull with the elbow and let the blade move.

Can rhomboid exercises fix my posture or a pain between my shoulder blades?

This page is about training and doesn't make that promise. For pain, see a doctor or a physical therapist.

How many rhomboid sets a week?

There is no rhomboid-specific number in the studies cited here. The 2026 stand's ten or more sets per muscle group a week is for muscle groups,⁸ so count rows and reverse flys toward your back total.

If you'd rather not plan it alone

A couple of rows and a reverse fly are simple; fitting them around your presses and your pulldowns so the week stays balanced is the part a page can't do. Coaching is the version where your workouts are built around the days you actually have, and a weekly call looks at the week you just had and rebuilds the next one. Coaching to build muscle explains how that works, and here's how to apply. Otherwise: add two sets of a second row to your next back day.
