Bent Over Low-Pulley Side Lateral
Also works: Lower Back · Middle Back · Traps
A one-arm rear-delt raise done bent over a low pulley, with the free hand braced on your thigh. Because the cable pulls from the floor rather than straight down, tension stays on the rear delt at the top of the arc instead of falling to zero the way it does with a dumbbell.
Own the movement
Set up first, then execute. Every cue below is something you can check on your next set.
Before the first rep
- Set the pulley at its lowest position and stand about a stride to the side of it, holding the handle in the far hand.
- Hinge until your torso is close to parallel with the floor, knees softly bent, back flat.
- Plant the free hand on the lower thigh of the same-side leg and take real weight through it.
- Let the working arm hang straight down and across, so the cable crosses under your chest at the start.
- Set a fixed 10-20 degree bend in the working elbow and refuse to change it for the rest of the set.
Every rep
Breathing & tempo — Exhale as the arm sweeps out, inhale on the way down. One second up, a one-second hold at the top, two to three seconds down — the slow lowering is where the tension actually accumulates.
Sets, reps & load
Where to start, and what to change when it stops being hard.
Start at the lightest plate on the stack — for most people that is 2.5-5 kg — and expect the useful working load to stay under 10 kg indefinitely. This is a muscle the size of your palm. Add reps up to 20 before you touch the pin, and only move up when every rep reaches ear height with a still torso.
What goes wrong
The errors that show up most often, and the cue that fixes each one.
Cut the weight by a third and hold the chest at a fixed height for the whole set. If your torso rises during the rep, that rep did not count.
Lock a slight elbow bend at setup and imagine the arm is a single rigid bar from shoulder to handle. Film one set from the front to check it.
Before each rep, set the shoulder blade down away from your ear and keep it there. If it rides up, the load has outgrown the rear delt.
Aim the knuckles at the wall behind you and slightly out. Standing a little further from the pulley makes the correct path more obvious.
Why bother
The rear delt is a small muscle worked through a short arc, which makes the tension curve matter more than the load. A bent-over dumbbell raise gives you almost nothing in the bottom third and everything at the top. Running the line from a low pulley in front of you flattens that out, so the rear delt is loaded from the hanging position all the way to shoulder height.
Working one arm at a time buys you something else: the free hand on your thigh props up the torso, so you can hold the bent-over position for 12-15 reps without your lower back deciding when the set ends. Two-handed versions almost always end because the erectors give out first.
Where it fits
Late in a pull day or a shoulder day, after rows and presses, in the 12-20 rep range. Two to three sets per arm, twice a week, is plenty. Do not pair it in the same session with heavy deadlifts — the bent-over position asks your lower back for the same thing at the worst possible time.

Asked and answered
Can I just do this with a dumbbell?
You can, and the arm path is identical, but the loading is not. A dumbbell hanging from a bent-over torso pulls straight down, so resistance is close to zero at the bottom and maximal only at the top of the arc. The low pulley pulls forward and slightly up, which keeps the rear delt loaded from the hanging position onward and gives you a real stretch at the start. If a cable station is free, use it; if it is not, a dumbbell version with a three-second lowering phase is a fair substitute.
How high should the arm go?
Level with your ear, arm parallel to the floor, and no higher. Going beyond that just recruits the traps and rhomboids to pull the shoulder blade back. The rear delt's job in this movement is finished at horizontal.
Should I feel this in my upper back rather than my shoulder?
Some upper-back involvement is normal, but if it dominates you are almost certainly pulling the shoulder blade back instead of moving the arm at the shoulder joint. Lighten the load and think about the upper arm swinging while the shoulder blade stays quiet.
Do I need this if I already row heavy?
Probably yes. Rows drive the elbow back along the ribs, which loads the lats and mid-back far more than the rear delt. The flared, out-and-back path here is what the rear delt actually does, and it is the head most people under-train relative to the front.
