The wide grip barbell bicep curl is a single-joint elbow flexion exercise performed with the hands set wider than shoulder-width on a straight barbell. The wider hand spacing shifts more emphasis onto the short (inner) head of the biceps brachii compared to a standard shoulder-width curl, giving the arms a fuller look from the front. Because the wide grip shortens the range of motion at the shoulder, it also reduces momentum from the front delts, keeping tension focused on the biceps.
Muscles Targeted
- Primary: Biceps brachii (short head emphasis)
- Secondary: Brachialis, brachioradialis
- Tertiary: Wrist and forearm flexors
Starting Position
Stand with feet shoulder-width apart and grip a straight barbell with an underhand (supinated) grip, hands set about 1.5 times shoulder-width apart. Let your arms hang fully extended with the bar resting against your thighs, elbows close to your torso. Keep your chest up, shoulders back, and core braced before starting the curl.
Execution Steps
- Brace your core and pin your elbows to your sides to prevent them from drifting forward
- Curl the bar upward by flexing at the elbow only, keeping the upper arms stationary
- Continue lifting until the bar reaches roughly chest or shoulder height
- Squeeze the biceps briefly at the top of the movement
- Lower the bar back down under control to full arm extension
- Repeat for the desired number of reps without letting the bar bounce off the thighs
Form Cues
- Keep elbows fixed at your sides: Letting them swing forward turns the curl into a partial shoulder movement and reduces bicep isolation
- Avoid using your back: Do not lean back or use hip momentum to help lift the bar
- Move through a full range: Lower until the arms are fully extended and curl until you reach full contraction
- Keep wrists straight: Avoid excessive wrist flexion or extension, which can strain the forearm tendons
- Control the eccentric: Lower the bar over 2-3 seconds rather than letting it drop
Common Mistakes
- Swinging the torso to generate momentum: This shifts work away from the biceps and adds lower-back strain. Use a lighter weight and keep the torso still.
- Letting the elbows drift forward: This recruits the front delts and shortens the effective range for the biceps. Keep elbows pinned close to your sides throughout.
- Using a partial range of motion: Stopping short at the top or not fully extending at the bottom reduces the growth stimulus. Complete the full range on every rep.
- Choosing too much weight: An overloaded bar forces cheating form and increases injury risk to the elbows and lower back. Select a weight that allows strict form for all reps.
- Flexing the wrists during the curl: This adds unnecessary forearm strain and reduces bar control. Keep the wrists locked in a neutral line with the forearm.
Variations
- EZ-bar wide grip curl: The angled grip of an EZ-bar reduces wrist strain while keeping the wide-grip emphasis
- Wide grip preacher curl: Performed on a preacher bench to remove momentum and increase strict bicep isolation
- Standing wide grip cable curl: Cable resistance provides constant tension throughout the range instead of peak tension at the midpoint
- Close grip barbell curl: Narrower hand spacing shifts emphasis toward the long (outer) head of the biceps for comparison
- Seated wide grip dumbbell curl: Dumbbells allow independent arm movement and correction of side-to-side imbalances
Tips for Progression
- Add small weight increments (2.5-5 pounds per side) once all reps can be completed with strict form
- Slow the eccentric phase to 3-4 seconds to increase time under tension without adding load
- Add a one-second pause at peak contraction to intensify the top portion of the lift
- Increase training volume with additional sets before increasing weight if grip or elbow strain limits progress
Training Notes
Program the wide grip barbell bicep curl 1-2 times per week as part of an arm or pull-focused session, typically after back exercises that already involve some bicep recruitment. Work in the 8-12 rep range for 3-4 sets, resting 60-90 seconds between sets. Pairing it with a close-grip or hammer curl variation across the week gives more complete development of both heads of the biceps.
