For building a wider back, the lat pulldown is the better tool for most men right now. You can load it precisely, add weight in small steps and take every set close to failure. If you can already do three sets of eight to ten clean pull ups, pull ups are just as good.
Search this and every result ends on the same line: both are great, use both. It sounds balanced. It does not help you decide what goes first in your back session or which one to push hardest. Here is a straight verdict, a decision rule you can apply in one sentence, and the reasoning behind both.
Which One Builds a Bigger Back?
The lat pulldown, for most men. Not because it is a better exercise in the abstract, but because of what it lets the average lifter actually do.
Your back grows from mechanical tension, and tension comes from taking sets close to failure. The deciding question is which exercise lets you do that, repeatedly, with your lats as the limiting factor. For most men that is the pulldown.
A set of pull ups is limited by whatever runs out first. For many men that is grip, bodyweight or simply not being able to do enough reps. If you can only manage four ragged pull ups, you are getting four reps of stimulus that end when your technique collapses, not when your lats are finished. On a pulldown you pick a weight you can do eight clean reps with and push until the lats are genuinely done.
Pull ups are not inferior. Once you are strong enough to do multiple hard sets of them, they are every bit as good. The verdict is about where most men are right now.
How Do They Compare on the Four Criteria?
An exercise is good enough for building muscle when it loads the right movement pattern, gives you enough stability, is kind to your joints, and lets you reliably add weight or reps. Both pull ups and pulldowns train the same pattern. The difference shows up in the last criterion.
| Criterion | Pull Up | Lat Pulldown |
|---|---|---|
| Movement pattern | Vertical pull, arm down and in | Vertical pull, arm down and in |
| Stability | Moderate, the body can swing | High, thighs pinned |
| Joint friendly | Good with control | Good with control |
| Easy to progress | Hard, you are stuck at bodyweight | Easy, small weight jumps |
| Verdict for most men | Great once strong | First choice now |
The pulldown wins on progression, and progression is the whole engine of growth. You can move from 50 kg to 52.5 kg on a pulldown. You cannot remove 2.5 kg of your own body. The same reasoning decides most equipment questions, as we cover in free weights versus machines.
Why Does Your Bodyweight Get in the Way?
Because with a pull up the minimum load is you. That is fine if you are light and strong, and a real problem if you are neither.
A heavier or less experienced lifter starts pull ups already near his limit. Every set becomes a fight for one or two more reps, so the rep range and the effort are dictated by his bodyweight rather than chosen for growth. Adding volume is almost impossible, because each set leaves him with fewer reps than the last.
The pulldown removes that ceiling. You choose the load, you choose the reps, and you can accumulate real work across three or four hard sets. For a man building his back from scratch, that control is worth more than the prestige of the pull up.
A review of loading recommendations found that muscle growth is similar across a wide span of loads, from roughly 30 percent to more than 80 percent of your one rep maximum, provided sets are taken close to failure.

Which Muscles Actually Do the Work?
Largely the same ones. Both train the lats as the main mover, with the biceps, rear shoulders and upper back helping.
A study comparing chin ups and lat pulldowns reported broadly similar activation of the latissimus dorsi between the two, with the differences lying mainly in the supporting muscles and the mechanics of the movement.
Source: Doma, Deakin and Ness, Sports Biomechanics, 2013So you are not choosing between two different back exercises. You are choosing between two ways of loading the same muscle, and the one you can load and progress more precisely wins for most men. Pull ups ask more of your trunk and grip, which is useful but is not back width. For more options once you have these sorted, see our list of the best back width exercises.
When Are Pull Ups the Better Choice?
When you can already do three sets of eight to ten clean reps. At that point bodyweight is no longer the limiting factor and pull ups deliver everything the pulldown does, plus more trunk and grip work.
From there, you can progress them by adding weight with a belt or a dumbbell between your feet, which solves the progression problem. Weighted pull ups are an excellent back exercise.
They also make sense if you train at home or in a gym without a pulldown machine. A bar is cheap and everywhere. If that is your situation, use assisted variations or slow controlled lowering to build up, rather than grinding out half reps. The mechanism behind all of this is covered in how muscle growth works.
How Should You Use Them for a Wider Back?
Here is the decision rule in one line: if you cannot do three sets of eight to ten clean pull ups, make the pulldown your main vertical pull, because it will build your back faster right now.
Your back sits at the mid to upper end of the weekly range of three to ten direct sets per muscle, so it can take a decent amount of work. Split that across two sessions, one vertical pull and one horizontal row in each. Six to ten reps, full stretch at the top, pull your elbows down and in, and stop about one rep short of failure.
Your biceps work hard on every one of these reps, which is one reason they need less direct work than most men give them, as we explain in why your arms are not growing. Log every set, add a small jump in weight when you can, and keep the same exercise for months so you can see it moving.

Are pull ups better than lat pulldowns for hypertrophy?
Not for most men. Both train the lats similarly, but the pulldown lets you choose the load, add weight in small steps and take every set close to failure. Pull ups are limited by bodyweight and grip until you are strong. Once you can do several hard sets of them, they build muscle just as well.
Are pull ups harder than lat pulldowns?
Usually yes, because the minimum load on a pull up is your whole bodyweight and you also have to control your trunk. On a pulldown you pick the weight. Harder does not mean better for growth. What matters is taking sets close to failure through a full range.
Do pull ups and lat pulldowns work the same muscles?
Largely, yes. Both load the lats as the main mover, with the biceps, rear shoulders and upper back assisting. Pull ups add more trunk and grip demand. They are two ways of loading the same movement pattern rather than two different back exercises.
Are chin ups better than lat pulldowns?
The same rule applies. Chin ups use an underhand grip that brings in more biceps, but they share the pull up's problem: your bodyweight sets the minimum load. If you cannot do three sets of eight to ten clean chin ups, the pulldown will build your back faster.
Can lat pulldowns replace pull ups?
For building back muscle, yes. A pulldown trained through a full range, close to failure and progressively will build a wide back without a single pull up. You would only miss the extra trunk and grip work, which you can get elsewhere.
What grip should you use on the lat pulldown?
A grip slightly wider than your shoulders is a sound default. Extremely wide grips shorten the range of motion without adding much. Pick one grip that lets you get a full stretch at the top and pull your elbows down to your sides, then keep it constant so your log stays comparable.
