Weighted One Hand Pull-Up

Body Part: Back

Muscle: Back

Equipment: Weighted

Weighted One Hand Pull-Up is a heavy unilateral vertical pulling exercise built around a single working arm on an overhead bar while the other hand holds a dumbbell at your side. It trains the lats, upper back, biceps, forearms, and the shoulder stabilizers that keep the torso from folding or spinning as you pull. The extra load in the free hand changes the demand on the trunk and shoulder, so the setup matters as much as the rep itself.

The image shows the body hanging from one arm with the working shoulder packed down, the non-working hand carrying a dumbbell, and the legs crossed behind to help keep the body quiet. That shape is the point of the exercise: you want a long, controlled hang at the bottom, then a strong pull that brings the chest upward without shrugging or swinging. A small amount of rotation is normal, but the rep should still look deliberate and under control.

Use this movement when you want advanced one-sided pulling strength and better body control at the top of a pull-up. Keep the ribcage stacked, avoid letting the shoulder drift up toward the ear, and think about driving the elbow down and back toward the hip. The working arm should do the lift, while the trunk resists the temptation to twist open too far or kip through the hardest part of the rep.

Lower yourself slowly to full extension and reset before the next repetition. Because the exercise is demanding on the elbow, shoulder, and grip, it rewards crisp execution more than volume. Use a load and rep target that let you keep the hanging shoulder organized, the free arm quiet, and the descent controlled from start to finish. If the position breaks down, the set is too heavy or the range is too aggressive for that day.

Instructions

• Grip the pull-up bar with one hand and let the other hand hold a dumbbell straight down by your side.
• Cross your ankles behind you or bend the knees slightly so the legs stay quiet and out of the way.
• Start from a dead hang with the working shoulder set down away from your ear and the ribs stacked.
• Brace your midsection before you pull so the torso does not swing open or over-rotate.
• Drive the elbow down and back as you pull your chest toward the bar.
• Keep the free hand still with the dumbbell hanging vertically instead of reaching or swinging.
• Pause near the top when the chin or upper chest is close to the bar and the shoulder still feels packed.
• Lower yourself under control until the working arm is fully extended, then reset before the next rep.

Tips & Tricks

• Keep the working shoulder depressed at the bottom; shrugging up usually turns the rep into a neck-and-trap fight.
• Let the dumbbell act as a counterbalance, not a pendulum. If it swings, the rep is probably too fast.
• A slight body angle is fine, but avoid turning the exercise into a full twist or side kip.
• Think about pulling the elbow toward the same-side hip, which helps the lat stay on task.
• Use chalk or a secure handle if grip starts limiting the set before the back does.
• Slow down the lowering phase so the shoulder can own the full range instead of dropping out of position.
• Keep the neck long and neutral; craning the chin forward usually shortens the working range.
• Stop the set when you can no longer control the hanging shoulder or keep the free arm quiet.

Frequently Asked Questions

What does Weighted One Hand Pull-Up train most?

It primarily targets the lats, with major help from the upper back, biceps, forearms, and shoulder stabilizers.

Why is the free hand holding a dumbbell?

The dumbbell adds load and changes the balance demand, so your trunk and shoulder have to resist rotation while you pull.

Should my body stay perfectly straight during the pull?

No, a little rotation is normal, but the torso should stay controlled and should not swing or kip.

How should I start each repetition at the bottom?

Begin in a controlled hang with the shoulder packed down, the ribs stacked, and the dumbbell hanging still by your side.

What is a common mistake with the top position?

Shrugging the working shoulder toward the ear or reaching the chin forward to fake extra height.

Is this exercise safe for beginners?

Usually not as a true strength drill. Most beginners should build to strict pull-ups and unilateral hanging control before trying this version.

How close should my chest get to the bar?

As close as you can reach without losing shoulder position, body control, or a clean descent.

What should I do if the dumbbell swings?

Reduce the load or slow the tempo until the free arm stays quiet and the body stops swinging.
