The Weighted One Hand Pull up is an elite-level unilateral pulling exercise that targets the latissimus dorsi as the primary mover, with significant contribution from the brachialis, brachioradialis, teres major, posterior deltoid, infraspinatus, teres minor, and both the middle and lower trapezius fibers. Additional load via a weight belt or weighted vest makes it one of the most demanding tests of single-arm pulling strength available to advanced calisthenics and strength athletes.
How to do the Weighted One Hand Pull up
- 1Attach a weight belt or don a weighted vest to add the desired load, then grip a pull-up bar with one hand using a full, closed grip — pronated, supinated, or neutral depending on your preference and bar availability.
- 2With the working arm fully extended, hang in a dead-hang position so your shoulder is fully depressed and your core is lightly braced; allow any swing to settle before beginning the pull.
- 3Place the non-working hand on the wrist of the working arm (or lightly on the bar near the working hand) to provide minimal counter-balance and tension control — do not use it to assist the pull.
- 4Initiate the movement by depressing and retracting the scapula of the working shoulder, then drive your elbow down and back toward your hip as if trying to put it in your back pocket.
- 5Continue pulling until your chin clears the bar or your chest approaches it, keeping your torso upright and avoiding excessive lateral lean or rotation.
- 6Hold the top position briefly with the elbow fully flexed and the shoulder in a packed, stable position.
- 7Lower yourself under full control back to the dead-hang position over 2–3 seconds, resisting the pull of the additional weight throughout the eccentric phase.
- 8Complete all reps on one side before switching arms, or alternate sides between sets depending on your programming.
Form tips
- Initiate every rep from a true dead hang — skipping the full extension shortens the range of motion and reduces lat recruitment at the lengthened position where most of the training stimulus occurs.
- Think of the movement as pulling your elbow to your hip rather than pulling your chin to the bar; this cue keeps the lat as the dominant mover and prevents the biceps from taking over.
- Keep the non-working hand as light as possible on the wrist — it should provide balance only, not a meaningful upward force; progressively reducing the assist over weeks is how you progress toward an unassisted one-arm pull-up.
- Brace your core and squeeze your glutes throughout the set to prevent the hips from swinging, which would reduce tension on the lat and increase spinal loading under the added weight.
- Treat this as a maximal-effort strength lift: warm up the shoulder, elbow, and wrist thoroughly, keep sets low (1–3 reps), and never train to failure — the eccentric load under extra weight places extreme stress on the biceps tendon and elbow joint.
Common mistakes
- Using the assisting hand to pull: pressing down or gripping the bar with the non-working hand to actively assist the rep converts the exercise into a partially assisted pull-up, undermining the unilateral strength stimulus and masking actual strength gaps between sides.
- Excessive lateral lean or rotation: tilting the torso sharply toward the working arm reduces the effective range of motion and shifts load away from the lat onto the obliques and spinal stabilizers, increasing injury risk at the shoulder under heavy loads.
- Skipping the dead hang at the bottom: cutting the range of motion by not returning to full arm extension shortens the eccentric phase and reduces the stretch-reflex stimulus that drives lat hypertrophy and strength at long muscle lengths.
- Adding weight before the base movement is solid: athletes who have not yet achieved a clean, controlled bodyweight one-arm pull-up should not add external load — the additional stress on the biceps tendon, elbow joint, and rotator cuff is disproportionate when technique is not established.
- Rushing the eccentric: dropping quickly to the bottom eliminates one of the most productive phases of the lift; a controlled 2–3 second lowering under the added load is where significant strength and tendon adaptation is built.
Frequently asked questions
What muscles does the Weighted One Hand Pull up work?
The latissimus dorsi is the primary target, responsible for shoulder adduction and extension during the pull. Key synergists include the brachialis, brachioradialis, teres major, posterior deltoid, infraspinatus, teres minor, and the middle and lower fibers of the trapezius, all of which contribute to elbow flexion, shoulder stability, and scapular control under unilateral load.
How much weight should I add to a one-arm pull-up?
Start conservatively — 5 to 10 kg (roughly 10–22 lb) is a meaningful challenge for athletes who can already perform multiple clean bodyweight one-arm pull-ups. Prioritize technique and controlled eccentrics over maximum load, and increase weight only when you can complete each rep through a full range of motion with no significant lateral lean.
Is the Weighted One Hand Pull up safe for the elbow and shoulder?
It can be safe when approached progressively, but it places extreme demands on the biceps tendon, elbow joint, and rotator cuff. Thorough warm-up, low rep ranges, avoidance of failure, and a solid base of unweighted one-arm pull-up strength are essential prerequisites for training this variation without injury.
What is the difference between a one-arm pull-up and a one-arm chin-up?
A one-arm pull-up uses a pronated (overhand) grip, which emphasizes the latissimus dorsi and reduces biceps contribution. A one-arm chin-up uses a supinated (underhand) grip, which recruits the biceps more actively and is generally slightly easier for most athletes due to greater biceps involvement in elbow flexion.
How do I progress toward a Weighted One Hand Pull up?
Build a foundation with archer pull-ups, one-arm negatives (controlled 4–5 second eccentrics), and band-assisted one-arm pull-ups before attempting the unweighted version. Once you can perform 3 or more clean bodyweight one-arm pull-ups with a full range of motion, begin adding modest external load via a weight belt and progress gradually from there.
