One Arm Lat Pulldown
The one-arm lat pulldown pulls a single cable handle down toward your shoulder, training your lats to do the work one side at a time instead of together. Because only one arm pulls, you have to actively resist the cable trying to twist or lean your torso, which adds a stability demand a two-handed pulldown doesn't. It suits beginners building back strength who want to check that both sides pull evenly, since a two-handed bar can let a stronger side do more of the work without you noticing.
Why it works
Pulling a cable handle down toward your shoulder draws your shoulder blade down and back, which is what puts the lats under tension through a long, controlled range. With only one arm on the cable, your obliques and lower back have to hold your torso square against the sideways pull, and your grip and forearm are doing all the holding rather than sharing it across two hands. That single-sided setup also makes it obvious if one side is weaker or less controlled than the other, something a bar pulldown can hide.
Set up
- Attach a single handle to a high cable and sit facing the machine, knees secured under the pad.
- Grip the handle with one hand, arm extended fully overhead.
- Sit tall with your ribs stacked over your hips before the first pull.
- Keep your free hand resting on your thigh or the seat for light balance.
How to do it
- Pull the handle down toward your shoulder, leading with your elbow.
- Keep your torso upright, resisting the urge to lean or twist away from the pull.
- Squeeze your shoulder blade down and back as the handle reaches your shoulder.
- Pause briefly at the bottom of the pull.
- Extend your arm back up with control, letting your lat stretch at the top.
- Complete all reps on one side before switching arms.
Form cues
- Elbow leads the pull down.
- Torso stays square, no leaning.
- Squeeze the shoulder blade, not just the arm.
- Control the stretch back up.
Breathing: Exhale as you pull the handle down, inhale as you extend your arm back up.
Common mistakes
Leaning the torso away from the cable to help pull the weight down.
Fix: Keep your ribs stacked over your hips and let your lat do the pulling; if you're leaning, the weight is too heavy for strict form.
Pulling mostly with the forearm and bicep instead of the shoulder blade.
Fix: Start the pull by drawing your shoulder blade down and back, then let your elbow follow that motion.
Letting the cable yank your arm back up quickly at the top.
Fix: Control the return the same way you controlled the pull; a fast release skips the stretch that builds range of motion.
Rotating the torso toward the working arm during the pull.
Fix: Brace lightly through your core and keep both shoulders facing the machine throughout the set.
How to program it
- As a supported cable movement rather than a free-weight lift, 2 or 3 sessions a week fits comfortably into most back-training splits.
- 3 or 4 sets of 10 to 15 reps per arm builds control and evens out any left-right strength gap.
- Pair it with a horizontal pull like a seated row in the same session to train your back through two different pulling angles.
- If one side needs noticeably more reps to reach failure, spend extra sets on the weaker arm rather than matching volume automatically.
Safety notes
- Keep the weight light enough that you can control the return without the cable jerking your shoulder.
- Stop the set if your torso has to twist significantly to complete the pull; that's a sign the load is too heavy for one arm.

Frequently asked questions
How many reps of one-arm lat pulldown should I do?
10 to 15 reps per arm for 3 or 4 sets is a solid range for building lat strength and control.
Why use a one-arm lat pulldown instead of the regular bar version?
Pulling one side at a time makes it obvious if one arm is weaker or pulling with worse form, since a bar lets a stronger side take over without you noticing.
Can I do a one-arm lat pulldown without a cable machine?
A one-arm dumbbell row trains the same lats and biceps from a hinge position and works well without a cable machine.
Why does my torso twist when I do a one-arm lat pulldown?
The cable is pulling toward one side, and if your core isn't bracing against that pull, your torso rotates to follow it. Lighten the weight and focus on keeping both shoulders square to the machine.
What grip should I use for a one-arm lat pulldown?
A neutral or slightly angled handle usually feels most natural for a single arm, since it lets your shoulder move through its own path instead of matching a fixed bar grip built for two hands.
