Uneven Pull-Up

The uneven pull-up is the bridge between two-arm and one-arm work. One arm takes the bulk of the load while the low hand offers just enough support to complete the rep and control the descent. Lower the support hand over time to shift more work onto the primary arm.

How to do it

  1. 1

    Grip the bar normally with your working arm, thumb wrapped.

  2. 2

    Hang a towel over the bar or grab the working forearm or wrist with the other hand so it sits lower.

  3. 3

    Depress and set the top shoulder, then pull hard through the high arm, letting the low hand assist as little as possible.

  4. 4

    Drive your chest toward the bar and keep the hips square rather than piking to one side.

  5. 5

    Lower slowly under control to a dead hang, keeping tension on the working side.

  6. 6

    Complete the reps, then switch which arm is high and repeat.

Tips

  • Keep the low hand as low as you can still tolerate; the higher it sits, the more it helps.
  • Do not let the pelvis twist away from the working arm, keep it stacked under the bar.
  • Match total reps on both sides to avoid building a strength imbalance.

Variations

Common mistakes

  • The low hand creeps up toward the bar across a set, and a few inches of height is the difference between a hard single-arm rep and an ordinary pull-up.
  • The low hand grips and pulls rather than steadying, so both arms share the work and the working side never gets overloaded.
  • Hips pike toward the supporting side to shorten the distance, which makes the rep look complete while the working lat does less of it.
  • Reps stop at chest height instead of driving the chest to the bar, so the top range where one-arm strength is built gets skipped every time.
  • Only the dominant arm gets trained high, and the imbalance that creates is harder to undo than it is to avoid.
  • The towel slips mid-rep because it was draped rather than pinched; set it so the fabric bunches in the fist before the feet leave the floor.

Frequently asked

How many uneven pull-ups should you do per side when you are new to the exercise?
Start with 3 to 4 sets of 3 to 5 reps per arm once you have 8 to 10 strict two-arm pull-ups. Do the weaker side first while you are fresh, and match the reps on the strong side rather than chasing more. Rest two minutes between sides. Progress by moving the low hand further down, from the working arm's wrist to its forearm, then to a towel gripped lower and lower, which is a finer jump than swapping band thickness and keeps every rep strict.
What can I do instead of uneven pull-ups with no pull-up bar?
A sturdy doorway bar, a playground frame, a tree branch or a set of rings hung from a beam all work, since all you need is something to hang from plus a towel. With nothing overhead, single-arm inverted rows under a table edge train the same uneven pull with your feet on the floor, and heavy single-arm dumbbell rows cover the lat strength. Neither teaches the trunk to stop the twist, so add side planks if you go that route.
What is the uneven pull-up good for, and when should I pick something else?
It is the bridge between two-arm and one-arm pulling, letting you shift most of your weight to one lat while the low hand gives only enough help to finish the rep and control the descent. Calisthenics athletes, climbers and grapplers use it for that. Pick something else if your goal is back size, where two-arm weighted pull-ups give more total load, and avoid it while an elbow is painful, because the low hand's bent-arm position under load is demanding on that joint.
