Reverse Barbell Curl: Stronger Forearms, Bigger Arms & Better Grip

What Is the Reverse Barbell Curl?

Definition & Key Difference from Traditional Bicep Curls

The reverse barbell curl is a simple twist on a classic move.
Instead of turning your palms up, you flip your grip — palms face down.

That one change completely shifts the muscle activation. Instead of your biceps doing most of the work, your brachioradialis and forearms take over.
You’ll feel it after just a few reps.

How the Overhand Grip Changes Muscle Recruitment

The overhand grip puts your wrists, elbows, and outer arm under constant tension.
Your forearms stay flexed the entire time, giving you that dense, veiny look lifters chase.

Plus, it builds a stronger grip — which pays off when you move to heavier compound lifts.

Why the Reverse Curl Is Underrated but Essential for Arm Balance

Most people focus on bicep curls and skip anything that feels awkward.
That’s a mistake. The reverse barbell curl strengthens your supporting muscles — the ones that stabilize your arms and joints.

It’s not flashy, but it’s one of the smartest ways to even out your upper body strength.

Reverse Barbell Curl Muscles Worked

Primary Movers — Brachioradialis, Brachialis, and Biceps Brachii

The brachioradialis is your forearm’s MVP. It’s responsible for that thick, rope-like look near your elbow.
The brachialis sits underneath your biceps — the hidden muscle that adds width and density.

Together, these muscles make your arms not just stronger but visually fuller.

Secondary Muscles — Wrist Extensors, Forearms, and Stabilizers

This move doesn’t stop at your arms. Your wrist extensors, forearms, and even core stabilizers are forced to stay engaged.
That’s why your grip feels like it’s on fire mid-set — you’re working multiple layers of muscle at once.

Why Reverse Curls Strengthen Your Grip and Prevent Imbalances

Most lifters overtrain their biceps and undertrain their extensors.
Reverse curls fix that. By strengthening the muscles that open your hand and stabilize your wrist, you’ll balance out strength ratios and reduce injury risk.

Do Reverse Curls Work Forearms and Biceps Equally?

Not quite. Your biceps still assist, but this is a forearm-first movement.
Think of it as the foundation for everything else you do with your arms — especially when you need endurance, not just flex.

How to Do a Reverse Barbell Curl with Proper Form

Setup — Grip Width, Stance, and Posture

Stand with your feet shoulder-width apart.
Grab the barbell with an overhand grip, hands slightly wider than your shoulders.
Keep your elbows pinned close to your ribs, and lock your core.

Execution — Curling Movement, Elbow Positioning, and Tempo

Curl the bar toward your shoulders using control, not momentum.
Keep your wrists straight — they should never bend backward.
Pause briefly at the top to feel the squeeze before lowering the bar slowly.

Lowering Phase — Controlling the Eccentric for Muscle Growth

Lowering the bar under control is where most of the muscle growth happens.
Take about three seconds to return the bar to the starting position.
Don’t rush it — the tension here builds both strength and size.

Key Cues for Proper Wrist and Shoulder Alignment

Keep your shoulders relaxed and back.
If your wrists start to bend or ache, the bar might be too heavy — lighten the load and focus on form first.

Common Mistakes — Wrist Bending, Swinging, or Overloading

Don’t swing the bar.
If your upper body starts rocking like a pendulum, you’re using too much weight.
Stay strict, and you’ll feel every rep where it matters — in your forearms.

Reverse Barbell Curl Variations & Alternatives

Barbell Reverse Curl (Straight Bar or EZ Curl Bar)

The straight bar hits your forearms hardest.
The EZ curl bar is a great alternative if your wrists feel strained — same benefits, less pressure.

Dumbbell Reverse Curl for Unilateral Balance

Using dumbbells forces each arm to work independently.
This prevents one side from dominating and improves overall coordination.

Cable Reverse Curl for Constant Tension

Cables keep the muscle under tension throughout the range of motion.
Perfect for hypertrophy or finishers.

Preacher Reverse Curl for Stricter Form

Performing reverse curls on a preacher bench removes momentum and isolates the brachioradialis.
It’s tougher — but way more effective.

Zottman Curl — Supination Meets Pronation

Curl the weight up like a normal bicep curl, then rotate your wrists into a reverse grip as you lower.
This one move hammers both sides of your arm.

Reverse Curl 21s and Pause Reps for Advanced Lifters

For lifters chasing forearm endurance, 21s are brutal — and brilliant.
Seven low reps, seven top reps, seven full reps.
Your arms won’t know what hit them.

Wrist Extensions (Dumbbell or Barbell) for Accessory Strength

A strong wrist equals a stable lift.
Finish your arm day with these to bulletproof your grip.

Reverse Curls vs. Standard Bicep Curls

Muscle Activation Comparison — Biceps vs. Brachioradialis

Standard curls work your biceps peak, while reverse curls thicken your arms from the side.
Together, they create complete, well-rounded arms.

Which Is Better for Size, Strength, or Forearm Thickness?

If you want mass, don’t skip either.
If you want endurance and grip strength, reverse curls win every time.

How to Use Both Curls for a Complete Arm Routine

Try pairing them back-to-back.
Do 10 reps of standard curls, then switch to 10 reverse curls.
It’s a brutal superset that hits every fiber from every angle.

Reverse Grip Barbell Curl vs Hammer Curl — What’s the Difference?

Hammer curls use a neutral grip, targeting the biceps more.
Reverse curls use an overhand grip, isolating your forearms and improving your grip strength.

Programming & Training Tips

How Many Sets and Reps for Optimal Forearm and Arm Growth

3–4 sets of 10–15 reps works best.
You don’t need to go heavy — form and control matter more here than brute strength.

Frequency — How Often to Train Reverse Curls Each Week

Twice a week is plenty.
Add them to your pull days or finish your upper-body workouts with them.

Best Way to Combine Reverse Curls with Other Arm Exercises

Pair them with hammer curls, chin-ups, or Zottman curls for a complete forearm circuit.

Progressive Overload and Grip Variation Strategies

Increase reps before you increase load.
You can also alternate between EZ curl bars, straight bars, and fixed barbells for variety.

Example Arm Workout

• Reverse Barbell Curl – 3x12

• Hammer Curl – 3x10

• Zottman Curl – 2x15

• Wrist Extensions – 3x20

Equipment & Setup for Reverse Barbell Curls

Barbells

Choose from straight bars, EZ curl bars, or fixed curl barbells depending on wrist comfort.
Our best-selling fixed barbells (20–115 lb) from Troy, York, and VTX offer balanced weight and secure knurling — perfect for forearm-heavy lifts.

Weight Plates

Why Knurling, Balance, and Grip Thickness Matter

Knurling gives you traction without tearing your hands.
Thicker bars challenge grip strength — but start standard before you level up.

Benefits of the Reverse Barbell Curl

Builds Powerful Forearms and Grip Endurance

If you struggle holding a barbell during deadlifts or pull-ups, this is your fix.

Improves Wrist Stability and Reduces Injury Risk

Stronger wrists mean fewer strains when pressing or curling heavy.

It’s simple, efficient, and brutally effective.
One of the few exercises that delivers both function and form.

Safety Tips & Common Mistakes

Wrist Alignment

Keep your wrists straight — if they bend, reduce the weight.
