Wide-Grip Barbell Curl
How to Do a Wide-Grip Barbell Curl
Stand tall holding a barbell with a palms-up grip slightly wider than shoulder width.
Keep your feet planted, torso braced, and shoulders relaxed.
Let the bar hang in front of the thighs with the elbows comfortably extended.
Keep the upper arms near the sides as you flex the elbows and curl the bar upward.
Avoid deliberately flaring the elbows outward just because the grip is wider.
Pause near the top without leaning backward or lifting the shoulders.
Lower the bar slowly until the elbows return to a comfortable extended position.
Form Check & Technique
DO THIS (Technique Tips)
- Use a moderately wide grip rather than an extreme one.
- Choose wrist comfort before chasing a specific hand spacing.
- Keep your elbows controlled throughout the repetition.
- Use an EZ bar if the straight bar feels awkward.
- Progress load only while the same grip width and ROM remain repeatable.
AVOID THIS (Common Mistakes)
- Using an excessively wide grip — Fix: Move the hands closer until the wrists and elbows feel natural.
- Flaring the elbows outward — Fix: Keep the upper arms controlled rather than forcing them wide.
- Leaning backward to finish reps — Fix: Brace the trunk and reduce the weight.
- Letting the wrists extend under the bar — Fix: Keep the wrists reasonably aligned with the forearms.
- Using a shorter range just to keep the extreme grip — Fix: Choose a grip that allows a comfortable controlled ROM.
- Swinging the bar from the hips — Fix: Start each rep from a stable torso.
About Wide-Grip Barbell Curl
The wide-grip barbell curl is a standing biceps curl performed with the hands positioned outside shoulder width. It keeps the familiar palms-up barbell-curl pattern while changing hand, wrist, and elbow geometry. A moderately wide grip is usually more useful than an extreme grip, and both heads of the biceps continue to contribute rather than one head being completely isolated.
Wide-Grip Barbell Curl Muscles Worked
The wide-grip barbell curl primarily trains the biceps through elbow flexion.
- A wider hand position changes the wrist and upper-arm geometry compared with a standard or narrow grip, but it does not switch off one biceps head or completely isolate the other.

How Wide Should Your Grip Be?
Place the hands moderately outside shoulder width while keeping the wrists comfortable.
- You do not need to use the widest possible grip.
- If the wrists or elbows feel strained, move the hands inward slightly.
Wide-Grip vs Standard Barbell Curl
Both movements use a supinated grip and elbow flexion. The wide-grip version changes hand spacing and arm geometry, while the standard curl uses a more neutral shoulder-width position that many lifters find easier to load.
Wide-Grip vs Close-Grip Barbell Curl
The main difference is hand spacing.
- A wide grip places the hands outside shoulder width, while a close grip brings them inside shoulder width.
- Both still train the biceps and should be selected primarily for comfort, variety, and progression rather than promises of completely isolating one biceps head.
Straight Bar vs EZ Bar
An EZ bar can reduce wrist strain by allowing the hands to sit at an angle. If a wide grip on a straight bar feels uncomfortable, an EZ-bar variation is a practical alternative.
