Pull-Ups vs Lat Pulldown: Which Builds a Wider Back?

The Short Answer

There’s a reason every strong back you’ve ever seen was built with pull-ups. They’re harder, they recruit more muscle, and there’s something satisfying about hauling your own bodyweight over a bar that no machine can replicate. But here’s the thing — if you can’t do pull-ups yet (and plenty of people can’t), lat pulldowns are how you get there. And even once you can, pulldowns still have a job to do.

Muscles Worked

Muscle Group	Pull-Ups	Lat Pulldown
Latissimus dorsi	Primary	Primary
Biceps	Secondary	Secondary
Rear deltoids	Secondary	Secondary
Rhomboids / Mid-traps	Moderate	Moderate
Core	High	Low
Forearms / Grip	High	Moderate

Both exercises train the same primary muscles — the lats and biceps — through a vertical pulling motion. The key difference is that pull-ups demand significant core engagement to stabilise your body, while the lat pulldown machine handles that for you.

Technique

Pull-Ups

1. Grip the bar with hands slightly wider than shoulder-width, palms facing away (overhand)
2. Start from a dead hang with arms fully extended and shoulder blades relaxed
3. Initiate the pull by depressing your shoulder blades — think “put your shoulder blades in your back pockets”
4. Pull your chest towards the bar, driving your elbows down and back
5. Clear the bar with your chin, squeezing your lats hard at the top
6. Lower under control back to a full dead hang — no half reps
7. Avoid kipping or swinging unless you’re specifically doing CrossFit pull-ups

Lat Pulldown

1. Sit with your thighs secured under the pads, feet flat on the floor
2. Grip the bar slightly wider than shoulder-width (same as pull-ups)
3. Lean back very slightly — roughly 10-15 degrees
4. Pull the bar to your upper chest, leading with your elbows
5. Squeeze your shoulder blades together at the bottom of the movement
6. Return the bar under control — don’t let it yank your arms up
7. Keep your torso position consistent throughout the set

Pros and Cons

Pull-Ups

Pros:

• Bodyweight exercise — you can do them anywhere with a bar
• Superior core activation and total-body tension
• Build impressive relative strength (strength-to-bodyweight ratio)
• Multiple grip variations (wide, close, neutral, chin-up) for different emphasis

Cons:

• Many beginners can’t do a single rep
• Hard to add small increments — progressive overload requires a dip belt or weighted vest
• Heavier lifters are at a disadvantage regardless of strength
• Difficult to train close to failure safely when fatigued

Lat Pulldown

Pros:

• Adjustable weight makes progression straightforward
• Accessible for all fitness levels from day one
• Easy to train to failure without risk
• Multiple attachments (wide bar, V-bar, single handle) add variety

Cons:

• Less core engagement than pull-ups
• Machine removes the stabilisation component
• Can encourage sloppy form — leaning too far back turns it into a row
• Not as impressive on the gym floor (let’s be honest)

When to Use Each

Use pull-ups when:

• You can perform at least 5 clean reps
• You want to build functional upper body strength
• You’re training at home or outdoors with minimal equipment
• You’re tracking bodyweight strength progress

Use lat pulldowns when:

• You’re building up to your first pull-up
• You want to add back volume after pull-ups without grip fatigue
• You need precise load control for hypertrophy sets
• You’re rehabbing a shoulder and need a more controlled movement

The ideal approach:

• Start your back session with pull-ups (weighted if you can do 10+ reps bodyweight)
• Follow up with lat pulldowns for 3-4 sets of 10-15 reps to accumulate volume
• Use your 1RM calculator to track your weighted pull-up progress

The Verdict

Pull-ups are the superior exercise if you can do them — they build more total-body strength, require more core stability, and have a simplicity that machines can’t match. But lat pulldowns aren’t a lesser exercise; they’re a complementary one. Use lat pulldowns to build the strength for your first pull-up, then keep using them alongside pull-ups to add training volume without frying your grip.
