What muscles do negative pull-ups work?

The same ones a pull-up does. Your lats resist your arms being pulled back overhead, your biceps resist the elbows straightening, and your mid-back resists your shoulder blades being drawn apart and up. They are working while lengthening rather than shortening.

Why can I lower myself but not pull myself up?

Because a muscle can control more load while being stretched than it can produce while shortening. It is a property of muscle rather than anything about your technique, and it is the reason this exercise exists.

How slow should a negative pull-up be?

Three to five seconds, and slowest at the top where it is hardest. A descent that starts as a fall and finishes slowly has skipped the part that was worth doing.

Negatives or a resistance band for getting a first pull-up?

They help at opposite ends. A band assists most at the bottom of the hang, where the pull is hardest. A negative gives no assistance and loads you from the top, where you are strongest. Both in a week is a good answer.

How often should I do negatives?

Often enough to be regular, not so hard that you cannot repeat it. Lowering under load makes you sore, and that eases substantially with repeated exposure over a few weeks. Stopping while you can still control the descent is the practical rule.

Are negatives only for beginners?

No. The amount you can control lowering stays higher than the amount you can lift at every level, so weighted negatives remain a real method long after a bodyweight pull-up is easy.

Negative pull up

Also called Eccentric pull-up, Lowering pull-up, Negatives.

The short answer

A negative pull-up starts at the top, chin above the bar, and lowers you to a full hang over 3 to 5 seconds. Getting back up there is setup rather than the exercise: the demonstration pulls back to the top, and stepping off a box or jumping to it does the same job for anyone who cannot. The same muscles work as in a pull-up, only they are lengthening under load instead of shortening: your lats resist your arms being pulled back up overhead and your biceps resist your elbows straightening. A muscle can control more load being stretched than it can produce shortening, which is why this version is available to you when the full pull-up is not.

How to do it

Step oneGet to the top position of a pull-up however you can, stepping up from a box, jumping, or pulling yourself up, with your chin above the bar and your arms bent.
Step twoGrip the bar with an overhand grip, shoulder-width apart.
Step threeSlowly lower your body toward the starting hang position, taking 3-5 seconds to descend.
Step fourMaintain tension in your lats and arms throughout the descent, resisting gravity as much as possible.
Step fiveOnce your arms are straight, return to the top and start the next one.

What usually goes wrong

Each starts with what you would notice.

You get to the top and arrive at the bottom about a second later.

WhyGravity did the rep. A drop is not a fast negative, it is an absence of one, and it is the single most common way this exercise gets wasted.

FixCount out loud. Three seconds minimum, five is better. If you cannot slow it down at all, put a chair under you and take some weight through a toe on the way down until you can.

You fall for most of it and only slow down near the bottom.

WhyThe top is where holding yourself is hardest, so it is the part that gets skipped, and the slow section ends up in the range where you were already strong.

FixFight hardest in the first third. If your chin drops away from the bar immediately, start the descent from a lower position, chin at bar height rather than above it, and own that range before adding the top back.

You start with your shoulders already up around your ears.

WhyJumping to the top and hanging on with the arms alone leaves the shoulder blades unset, so your back is not holding anything from the first moment and the descent is all arms.

FixBefore you begin lowering, pull your shoulders down away from your ears and lift your chest slightly. Hold that as long as you can into the descent. Losing it partway down is fine and expected. Never having it is the problem.

You do them to complete failure every session and feel wrecked for days.

WhyLowering under load produces more muscle soreness than lifting does. That eases with repeated exposure over weeks, and hammering it in a single session is not what produces the adaptation.

FixStop each set while you can still control the descent, and come back to it twice a week rather than emptying the tank once. The soreness settles noticeably by the second or third week of regular exposure.

Negatives or a resistance band

These are the two standard answers for someone who cannot yet do a pull-up, and they help in opposite parts of the movement.

A band stretched between the bar and your foot or knee pulls hardest when it is most stretched, which is at the bottom of the hang. So it assists you most exactly where the pull is hardest, and least at the top where you need it least.

A negative gives you no assistance anywhere. What it does instead is put you in the position you are strongest in, the top, and ask you to resist from there. The load is highest at the start of the descent and eases as you go.

They are not rivals. The band lets you rehearse the whole pull including the bottom; the negative builds the ability to hold and control your bodyweight at all. Doing both in a week is a reasonable answer, and if you only have one, use the one you have.

Negatives or dead hangs

When a pull-up is a long way off, plenty of people just hang from the bar instead, and it is worth knowing what that does and does not cover.

A dead hang builds grip, gets your shoulders used to supporting your bodyweight, and is genuinely useful for both. What it does not do is ask your back to resist anything, because at a full hang with straight arms there is very little for the lats to hold.

A negative asks for exactly that. From the moment you start lowering, your back and arms are resisting your bodyweight through a range they will have to work through when you finally pull.

If you cannot yet hold a hang for twenty or 30 seconds, hangs first. Once you can, the negative is where the useful work moves to.

Why lowering is easier than lifting

The whole reason this exercise works rests on one fact about muscle, and it has been known since the 1880s: a muscle being stretched while it contracts can produce more force than a muscle shortening.

That is why you can lower yourself under control from a bar you cannot pull yourself up to. Nothing about you is different between the two directions except which way the muscle is moving, and one direction has a higher ceiling than the other.

It also means negatives are not only a beginner exercise, which is how they are usually filed. Because the eccentric ceiling stays higher than the concentric one at every level, adding weight and lowering slowly is a real training method for someone who can already do sets of pull-ups.

One honest caution. Eccentric training is sometimes sold with a striking figure attached: it is usually traced to a small cycling study in which an eccentric group gained muscle fiber size while a concentric group matched for metabolic cost gained none. That is one trial, in a different exercise. That is one trial and one result, and it should not be read as eccentric work being generally superior. Take the force asymmetry, which is settled, and treat the rest as interesting.

The practical thing to know is that lowering under load makes you sorer than lifting does, especially the first few times. That eases considerably with repeated exposure, which is a reason to be regular about it rather than heroic.

What it is for

The negative pull up is a bodyweight exercise targeting the lats, with secondary engagement of the biceps, traps, and rhomboids. It focuses on the eccentric lowering phase of the pull-up to build the back and arm strength required for a full pull-up.
