What is a sensible starting dose for the one-arm negative pull-up, and what should I be able to do first?

You should already own smooth, controlled two-arm negatives lasting eight to ten seconds, plus ideally a couple of strict weighted pull-ups, before trying the one-arm version. Start with 2 to 3 sets of 1 to 2 reps per arm, resting three minutes or more, and stop the set the moment the lower speeds up or the torso starts twisting. Add a second to the descent before you add a rep.

What can I do instead of one-arm negative pull-ups if I'm not ready for the full unassisted move?

A light band looped under the free hand for partial assistance, or archer pull-up negatives, both bridge the gap without loading one arm fully. If there's no bar available at all, a single-arm lat pulldown done as a slow negative trains the same pattern.

What does the one-arm negative pull-up train, and who should not attempt it yet?

It builds the eccentric strength and the elbow and shoulder tissue tolerance needed for a full one-arm pull-up. It is the wrong move for anyone without a solid two-arm pull-up already, and a poor choice for anyone with existing elbow or shoulder pain, since the unilateral load concentrates stress right at those joints.

Advanced

One-Arm Negative Pull-Up

Eccentric strength comes before concentric, which is why slow one-arm negatives are the classic entry to the full one-arm pull-up. They also teach your elbow and shoulder connective tissue to tolerate the huge unilateral load. Aim to make the lower longer and smoother before you chase a full rep.

How to do it

1
Jump, step off a box, or use both arms to bring your chin over the bar.
2
Release the assisting hand and take all the load on one arm at the top position.
3
Pack the shoulder down and keep the elbow slightly bent, do not let it snap straight.
4
Lower yourself as slowly as you can, aiming for a five second or longer descent.
5
Fight the tendency to rotate by bracing the abs and squeezing the glutes.
6
Reach a full dead hang, then reset for the next rep and switch arms across sets.

Tips

Keep tension in the shoulder the entire way down; a loose hang at the bottom stresses the elbow.
If you drop fast through the middle, you are not ready, shorten the range and control it.
Film your descent so both arms accumulate similar controlled time under tension.

Variations

Common mistakes

The elbow locks out straight the instant the assisting hand releases, jamming the joint under the full bodyweight load instead of sharing it with a packed shoulder.
The torso corkscrews toward the working arm halfway down as the obliques give up the brace, turning a straight lower into a twisting one.
Chasing a full five-count on the very first attempt, with a body that has never held one arm at the top, leads to a sudden collapse rather than a slow lower.
Switching arms every single rep instead of finishing a full set on one side never lets either shoulder accumulate enough time under tension to adapt.
The free hand grabs the bar for help halfway through the descent, which erases the entire point of loading one arm.
Continuing to grind through pinching or sharp elbow pain rather than plain muscle fatigue turns a strength drill into an overuse injury.
