The incline dumbbell row is a two-dumbbell row done lying face down on a bench set to 30 to 45 degrees. Your chest rests on the pad, your arms hang straight down, and you pull the weights towards your lower ribs. Since the bench holds your torso up, your lower back has no job to do, and the set ends when your back muscles give out rather than when your spinal erectors do. If you own an adjustable bench and a pair of dumbbells, it's arguably the most useful back exercise in your home gym.
This page is the how-to for the exercise itself, with most of the detail on bench angle and setup, because that's where most people get it wrong. For the wider family of supported rows (machines, T-bar, landmine), see our chest supported row guide; if you can't do this one, our chest supported row alternative roundup has the swaps.
The angle changes the exercise more than people expect, so it's worth a minute of fiddling before your first set.
| Bench angle | Torso position | What it suits | Watch out for |
|---|---|---|---|
| 30 degrees | Close to horizontal | Lats and mid-back, longest pull | Dumbbells may touch the floor if you're tall |
| 35 to 40 degrees | Middle ground | Most people, most of the time | Very little; this is the default |
| 45 degrees | More upright | Upper back, rear delts, wide-elbow rows | Traps take over if you shrug |
| Over 45 degrees | Nearly upright | Not recommended | Turns into a shrug and upright row hybrid |
Most adjustable benches don't print the angle on the spine, so judge it by the notches: on a typical home bench, 30 degrees is usually the first or second incline position above flat, and 45 is the one or two above that. A better test is functional. Lie on it, let your arms hang, and check that the dumbbells clear the floor by a few centimetres at full stretch. If they hit the floor, go one notch steeper or kneel on the seat. If they clear by a mile and your torso feels quite upright, drop a notch.
Bench stability matters here too. You're pushing your chest into an angled backrest and loading the front of the bench, which is the opposite of how it's loaded for pressing. A bench with a narrow front foot can rock. The JOROTO MD85 and the benches in our best weight bench UK guide all have wide enough bases for this, but check yours before you go heavy.
The one cue to remember
Push your chest into the pad harder as the set gets harder. The moment your sternum lifts off the bench, you've turned the exercise back into a bent-over row and your lower back is working again. If you can't keep contact, end the set there.
A 2026 narrative review of EMG studies on lat training concluded that the angle between the upper arm and torso may be a major factor in how load is shared between back muscles, and that a lower shoulder-abduction angle (elbows closer to the body) was linked to greater lat activity in the seated row (J Funct Morphol Kinesiol, 2026). The authors are careful to say these are short-term EMG readings rather than long-term training results, but the practical point fits what lifters feel: where your elbows go decides which muscles do the work, and on an incline row you control that completely.
This is the main reason to do it. In a lab comparison of three rows, the standing bent-over row produced the largest lumbar spine load of the group, while the inverted row, where the body hangs horizontally instead of holding a hinge, produced lower lumbar erector spinae activity and the lowest spine load (Fenwick, Brown and McGill, J Strength Cond Res, 2009). That study didn't test an incline bench row, so treat it as a principle rather than a direct measurement: when something other than your spine holds your torso, your lower back works less. The incline bench does exactly that.
In practice, you can do hard sets of incline rows the day after heavy deadlifts or squats, when a bent-over row would feel awful. And if your lower back is the thing that usually ends your rowing sets, this lets your back muscles get worked properly for once.
With your chest on a pad there's no hip drive, no torso swing and no bouncing the weights off your thighs. The weight you use is the weight your back can actually move, which makes progress easy to track from week to week.
Two dumbbells mean a weaker side can't hide behind a stronger one, as it can with a barbell. You'll often notice one dumbbell lagging at the top of the last few reps; that's useful information.
An adjustable bench and a pair of dumbbells, nothing else. A set of adjustable dumbbells covers the whole progression from light rear-delt work to heavy lat rows.
Bench too steep. The most common error. At 60 degrees or more you're mostly shrugging, and your upper traps and neck take over. Drop it to 30 to 45.
Lifting the chest off the pad. As fatigue builds, people arch up to get the dumbbells a little higher. That brings the lower back back in, which defeats the point. Keep your chest down and accept a slightly shorter range on the last rep.
Craning the neck to look forward. Lifting your head to watch yourself in a mirror kinks your neck. Look at the floor slightly ahead of the bench instead.
Cutting the bottom short. If your arms never straighten and your shoulder blades never spread, you miss the stretched part of the rep. Lower all the way.
Curling the weight up. If your biceps burn before your back does, you're pulling with your hands. Think of your hands as hooks and drive your elbows instead.
Going too heavy. Expect to use less than on a single-arm row. Heavier dumbbells with half reps train your ego more than your back.
Same setup, one dumbbell, with your free hand holding the side or top of the bench. You get a slightly longer range because your torso can turn a fraction towards the working side, and you can concentrate on one side at a time. Compared with the standard single-arm dumbbell row on a flat bench, your lower back and obliques have less to do, because the pad stops your trunk twisting.
Set the bench at about 45 degrees, take a pronated grip and flare your elbows out to around 70 to 90 degrees from your torso. Pull towards your upper chest instead of your ribs. The lats contribute less and the rear delts and mid-traps take the load, so go light, often half of your normal row weight. Our rear delt row guide covers this variation in more depth.
The seal row is the same idea taken further: you lie completely flat on a bench raised on boxes or plates, so your torso is horizontal and your arms hang straight down. That gives the most direct line of pull for the lats and removes every trace of momentum. The trade-off is setup, because you need about 40cm of clearance under the bench. The incline dumbbell row gets you most of the way there with a standard bench, and it lets you change the angle to bias the upper back.
The Kroc row is a single-arm dumbbell row done heavy for high reps, with deliberate body English: your hips and torso help heave the weight. It's close to the opposite of the incline row. Kroc rows train grip, trunk and the ability to grind out ugly reps under a heavy load; the incline row isolates the back and keeps the lower back out of it. Both have a place, but they aren't substitutes for each other, and if you're rowing to protect your lower back, Kroc rows aren't the answer.
Once or twice a week is plenty. Pair it with a vertical pull such as pull-ups or a lat pulldown so you're training the back from both directions. A simple progression: when you can do every set at the top of your rep range with the pause intact, move up to the next dumbbell and start again at the bottom of the range.
Set it between 30 and 45 degrees. Around 30 degrees puts your torso closer to horizontal, so the pull lines up well with your lats and mid-back, but taller lifters may find the dumbbells touch the floor. Around 45 degrees gives the weights more clearance and suits a higher, wider pull for the upper back and rear delts. Past 45, the movement drifts towards a shrug and upright row.
Your lats, rhomboids, mid and lower traps and rear delts do the pulling, with your biceps, brachialis and forearms assisting at the elbow. Because your chest rests on the bench, the lower back and hamstrings barely work, so nearly all the fatigue lands on the upper and mid-back.
It's the most common form of it. 'Chest supported row' covers any row where a pad holds your torso, including machines and T-bar setups. The incline dumbbell row is the version you can do at home with an adjustable bench and two dumbbells, and it's what most people mean when they say chest supported dumbbell row.
Feet on the floor for most people, planted wide with the toes dug in, so you can push your chest into the pad. If you're tall and the bench is low, kneeling on the seat can lift you high enough that the dumbbells clear the floor at full stretch. Either works as long as your chest never peels off the pad.
Expect to use noticeably less than you would on a single-arm dumbbell row, because there's no leg drive or hip rotation to help. Pick a weight you can row for 10 to 15 reps with a one-second squeeze at the top. If you need to jerk the first rep off the floor, it's too heavy.
Not better, just easier to set up. A seal row puts you fully horizontal on a raised flat bench, so it's the strictest version, but it needs boxes or a dedicated bench. The incline dumbbell row gives you most of the same lower-back relief with a standard adjustable bench.
