A landmine row done one hand at a time: one end of a barbell wedged in a corner or landmine sleeve, plates on the other, and you row that loaded end to your side from a hinge. The pivot at the far end forces the bar along an arc, which keeps the elbow tucked and the pull naturally in the groove.

How to

Own the movement

Set up first, then execute. Every cue below is something you can check on your next set.

Before the first rep

  • Wedge the empty end into a landmine sleeve, or into a corner with a heavy plate on top of it so it cannot skid out.
  • Load small plates rather than one big one — a 25 kg plate can leave no room for your hand near the collar.
  • Stand beside the bar, straddling nothing, and grip just behind the collar with the working hand.
  • Stand it up with your legs, then hinge back down: hips pushed back, chest up, arm hanging straight.
  • Set the feet staggered, working-side foot slightly back, so the bar has a clear path past your leg.

Every rep

01
Retract the shoulder blade first, then let the elbow bend and travel back along your ribs.
02
Row the collar to the side of your hip, following the arc the bar wants to take rather than fighting it upward.
03
Keep the torso still — the bar moves, your ribcage does not.
04
Pause a second at the top with the shoulder blade fully pulled back.
05
Lower over three seconds until the arm is straight and the shoulder blade has reached forward.

Breathing & tempo — Exhale as the bar comes to the hip, inhale on the way down. One second up, one second paused, three seconds down. Reset the brace at the bottom of every rep.

Before you load it

  • Secure the far end before every set. A bar that shoots out of a corner under load takes your grip and your balance with it.
Programming

Sets, reps & load

Where to start, and what to change when it stops being hard.

Strength
4-5 sets of 5-8 per arm
Hypertrophy
3-4 sets of 8-12 per arm
Endurance
2-3 sets of 15-20 per arm

Start with a single 10 kg plate and treat the number as a scale of its own — because the far end pivots, the weight in your hand is well under the plate total. Add 5 kg a side once you can pause the top of every rep for a second without your torso rising. Grip is the usual limiter past 40 kg; use straps rather than shortening the range.

Fix your form

What goes wrong

The errors that show up most often, and the cue that fixes each one.

Loading a single large plate so there is no room to grip near the collar.

Use 10 kg or 15 kg plates and stack them. Gripping further out the shaft lengthens the lever and turns a 40 kg row into an unmanageable one for no benefit.

The bar end skidding out of the corner mid-set.

Use a proper landmine sleeve if the gym has one. If not, drop a 20 kg plate flat over the bar end in the corner and check it has not crept after every set.

Standing up out of the hinge as the sets get heavy.

Keep your hips pushed back and your chest at a fixed angle; strip a plate rather than raising your torso. The arc only stays useful if your body angle stays constant.

Reading the plate weight as the load on your back.

Log the plate weight and let it be its own progression scale. Do not compare it to a dumbbell row — the pivot carries part of the load, so the numbers are not equivalent.

The case for it

Why bother

Because the far end of the bar is fixed, the loaded end travels on an arc rather than straight up. That arc pulls your elbow toward your hip as you row, which is the same path a good dumbbell row takes but here it is enforced by the equipment rather than by your attention.

The other advantage is loading granularity at the heavy end. You can put 60 kg of plates on the sleeve and only feel a fraction of it, because the pivot bears part of the weight — so this is the single-arm row that keeps working long after the gym's biggest dumbbell has stopped being a challenge.

Where it fits

A main horizontal pull for four sets of 6-10 per side, or a heavy finisher after chin-ups. Because you are hinged and unsupported, treat it as spinal work and keep it off the same day as heavy deadlifts, or put it late in that session with a lighter load.

Questions

Asked and answered

How much weight am I actually lifting?

Considerably less than the plates say — the fixed end carries part of the load, and how much depends on where along the shaft you grip. That is not a problem, but it means the number is only comparable to itself. Log it as a landmine number and progress it on its own scale.

Do I need a landmine attachment?

No. A corner works, provided you protect the wall and stop the bar sliding — a heavy plate laid over the end does the job. A proper sleeve is safer and quieter, and it lets you set up in the middle of the floor rather than fighting for the one usable corner.

Is this better than a dumbbell row?

It is better when the dumbbells run out or when you keep flaring your elbow, because the arc solves both problems. The dumbbell version gives a longer stretch at the bottom and lets the shoulder blade travel further forward. Neither is redundant; the landmine version is the one that scales further.

Should I brace my free hand on my knee?

You can, and it makes the hinge easier to hold at heavy loads by taking some torso weight through the arm. It also removes the anti-rotation demand. Keep the free hand off for lighter, higher-rep sets and put it on the knee for your top sets if the hinge is what fails first.
