Upright Row vs Shrugs: Which Builds Bigger Traps & Delts?

Have you ever stood in the gym, barbell in hand, wondering if upright rows or shrugs will finally give you that thick, powerful yoke?

You know—the kind of upper back and shoulder development that makes your T-shirt stretch and turns heads. You’re not alone. Thousands of lifters debate this every week. Today, we’re settling it once and for all: upright row vs shrugs—which is the best move for traps and delts?

As a certified personal trainer with over years of coaching real clients (from beginners to competitive bodybuilders), I’ve seen both exercises transform physiques—and I’ve also seen them cause unnecessary pain when done wrong.

So let’s break it down in plain English: no fluff, no bro-science, just facts, form tips, and a clear winner for your goals.

The Muscles We’re Talking About: Traps and Delts 101

Before we grab the bar, let’s talk about what we’re actually building.

Your trapezius (or “traps”) is that diamond-shaped muscle running from your neck down to your mid-back and out to your shoulders. It’s split into three parts:

• Upper traps: The ones that shrug your shoulders up to your ears.
• Middle traps: Pull your shoulder blades together.
• Lower traps: Help stabilize and depress your scapula.

Then come the deltoids—your shoulder caps. They’ve got three heads too:

• Front (anterior) delts: Help with pressing and lifting arms forward.
• Side (lateral) delts: Give your shoulders that wide, capped look.
• Rear delts: Often neglected, but crucial for posture and 3D shoulders.

Fun Fact: According to a 2021 study in the Journal of Strength and Conditioning Research, well-developed upper traps can increase perceived shoulder width by up to 18%—even without changing your actual bone structure.

Both upright rows and shrugs hit the upper traps hard, but they treat the delts very differently. Let’s see how.

The Upright Row – A Love-Hate Classic

The upright row is that move where you pull a barbell (or dumbbells) from your thighs up to your chin, elbows flaring out like wings.

Muscles Worked

• Main players: Upper traps, side delts
• Helpers: Front delts, biceps, forearms

How to Do It Right (Step-by-Step)

1. Stand with feet hip-width apart.
2. Grip the bar just inside shoulder width (or use an EZ-bar for wrist comfort).
3. Pull your elbows up and out, leading with the pinkies.
4. Stop when your elbows reach shoulder height—don’t go higher.
5. Lower slowly. No jerking.

Pro Tip: Keep the bar close to your body. Think “zipper line” from hips to chin.

Common Mistakes That Wreck Shoulders

• Raising elbows above shoulders (hello, impingement)
• Using a super narrow grip (wrist pain city)
• Swinging with momentum instead of muscle

Variations to Try

• Wide-grip upright row → More side delt, less stress on wrists
• Cable upright row → Smoother pull, constant tension
• Dumbbell upright row → Fix strength imbalances

The Good

• Hits side delts harder than almost any other pull
• Saves time—compound move for traps + shoulders

The Bad

• High risk of shoulder impingement, especially with poor mobility
• Not beginner-friendly

Real Client Story:
“I used to do upright rows every arm day. After 6 months, my right shoulder started clicking. Switched to wide-grip with lighter weight—pain gone in 3 weeks.” – Jake, 29, software engineer turned powerlifter

Shrugs – The Trap King

Shrugs are simple: hold heavy weight, lift your shoulders to your ears, lower. That’s it.

Muscles Worked

• Star of the show: Upper traps
• Supporting cast: Levator scapulae, middle traps (if you squeeze blades)
• Delts? Barely a cameo.

How to Do It Right

1. Grab dumbbells, barbell, or trap bar.
2. Let arms hang straight down.
3. Shrug shoulders straight up—like saying “I don’t know” with a 200 lb backpack.
4. Hold the top for 1 second.
5. Lower slowly—don’t drop.

Golden Rule: No rolling shoulders forward or backward. That’s a myth and can pinch nerves.

Variations to Keep It Fresh

• Trap bar shrugs → Most natural grip, heaviest loads
• Behind-the-back shrugs → More upper trap stretch
• Haney shrugs (lean forward 15°) → Hits middle traps harder
• Farmer’s carries → Functional trap burner

The Good

• Safest way to load traps heavy
• Nearly impossible to mess up
• Perfect for progressive overload

The Bad

• Doesn’t grow side delts much
• Can get boring fast

Stat Attack: A 2014 EMG study by Andersen et al. showed shrugs activate upper traps 12–15% more than upright rows at the same weight. That’s real muscle-building efficiency.

Head-to-Head: Upright Row vs Shrugs

Verdict?
If you want massive traps with minimal risk, shrugs win.
If you want wider shoulders and don’t mind extra caution, upright rows have a place.

What Science Says (EMG Studies & Injury Data)

Let’s go beyond gym lore.

• EMG Evidence (Schoenfeld, 2019): Upright rows light up lateral delts 25–30% more than shrugs. But shrugs crush upper traps by ~15%.
• Injury Risk (Kolber et al., 2010): Up to 1 in 5 lifters report shoulder pain from upright rows—especially with narrow grip and high elbows.
• Fix? Use a wide grip and stop at chin level. One study found this cuts impingement stress by 40%.

Who Should Do Which?

Do Upright Rows If:

• You want 3D shoulders (traps + capped delts)
• You have great shoulder mobility (test: can you do overhead press pain-free?)
• You use wide grip + perfect form
• You’re in a bodybuilding or physique phase

Do Shrugs If:

• Your #1 goal is a thick, meaty yoke
• You’ve had shoulder issues before
• You’re a beginner, powerlifter, or strongman
• You want to lift heavy without thinking

Smart Combo (My Favorite)

• Main Move: Shrugs (4 sets of 10–15) → Build the foundation
• Finisher: Light cable upright rows or lateral raises (3 sets of 12–15) → Polish the delts

How to Program Them (Sample Workouts)

Trap-Focused Pull Day

1. Deadlifts – 4×6
2. Barbell Shrugs – 4×12 (hold top 2 sec)
3. Face Pulls – 3×15
4. Farmer’s Carries – 3×30 sec

Shoulder Hypertrophy Day

1. Overhead Press – 4×8
2. Wide-Grip Upright Row – 3×10 (slow eccentric)
3. Lateral Raises – 3×12–15
4. Rear Delt Flyes – 3×15

Pro Tip: Traps recover fast. Train them 2–3 times per week with 10–20 total sets.

Avoid Pain: Mobility & Prehab Tips

Before touching upright rows, ask:

• Can you raise your arms overhead without arching your back?
• Do your shoulders click or pinch at 90°?

If no, skip upright rows until you fix it.

Daily Prehab Circuit (5 Minutes)

1. Band pull-aparts – 2×20
2. Scapular wall slides – 2×10
3. Doorway pec stretch – 2×30 sec/side

Testimonial:
“I couldn’t do upright rows without pain for years. After 4 weeks of your mobility routine, I’m back at it—pain-free and hitting PRs.” – Sarah, 34, CrossFit coach

Better Alternatives (If Neither Feels Right)

For Traps

• Rack pulls (just below knee)
• Kelso shrugs (on incline bench)
• Heavy farmer’s walks

For Delts

• Cable lateral raises
• Lean-away laterals
• Landmine press

All-in-One

• Snatch high pull → Explosive traps + delts
• Power clean → Athletic yoke builder

Myth Busting: Let’s Clear the Air

Final Verdict

Shrugs take the crown for building bigger, safer traps. They’re simple, heavy, and nearly bulletproof.

Upright rows are a solid #2—great for side delts, but only if you’ve got the mobility and form dialed in.

My Advice? Start with shrugs as your trap foundation. Add light, wide-grip upright rows only after 6–12 months of consistent training and zero shoulder issues.
