EZ Bar Curl (Wide Grip)
What Is the EZ Bar Curl (Wide Grip)?
EZ Bar Curl (Wide Grip) is an isolation exercise that primarily targets the biceps, with the biceps brachii as the main mover and the brachialis and brachioradialis helping to bend the elbow. It is a beginner-level movement performed standing, with the hands on the outer bends of an EZ bar, slightly wider than the shoulders.
Like other barbell curls, it is a staple for building biceps size and elbow-flexion strength. It usually sits near the end of an upper-body, pull or arm session, after the heavier compound lifts, and is trained for moderate to high reps with strict form.
The bends in an EZ bar turn the palms partway in instead of locking them fully palms-up the way a straight bar does. Many lifters find that easier on the wrists and elbows, which is the main reason to choose it. The trade-off is that the biceps also rotates the forearm palm-up, so the straight bar keeps it in its strongest position and the EZ bar gives up a little of that.
Taking the outer bends instead of the inner ones mainly changes how the bar sits in the hands and how far apart the forearms travel. Gyms often teach that a wide grip shifts the work to the short (inner) head of the biceps, but that is a coaching belief rather than an established fact, so pick between this and the EZ Bar Curl (Close Grip) for comfort and variety.
It suits beginners learning a strict curl as well as experienced lifters who want a joint-friendly barbell curl. Anyone who cannot keep the torso still with even a light bar can build the pattern first with the Dumbbell Curl or the Cable Curl.

Instructions
- Stand upright with your feet about hip-width apart and grasp an EZ bar with an underhand grip, hands on the outer angled sections so your palms face up and slightly inward.
- Keep your elbows close to your sides and let the bar hang in front of your thighs with arms fully extended.
- Exhale and curl the bar upward by flexing your elbows, keeping your upper arms close to your sides.
- Continue until your forearms are close to vertical and the bar is at about shoulder height, letting your elbows drift only slightly forward at the top.
- Squeeze your biceps at the top and hold for a brief moment.
- Slowly lower the bar until your arms are straight again, without letting it drop into the bottom.
- Repeat for the desired number of repetitions.
Common Mistakes
Swinging the weight
Momentum reduces the tension on the biceps and increases the chance of injury.
Swinging the elbows up
Heaving the elbows well forward to get the bar past the hard part turns the top of the rep into a front raise and hands work to the front delts.
Curling the wrists
Bending the wrists toward the forearms at the top shifts work to the forearm flexors and strains the wrists under load.
Dropping the bar on the way down
Letting the bar fall instead of lowering it under control wastes the lowering phase and jolts the elbows at the bottom.
Incomplete range of motion
Failing to fully extend or curl limits the effectiveness of the exercise.
Injuries
EZ Bar Curl (Wide Grip) is a low risk exercise when performed with proper technique. The load is modest and the movement simple, so most problems come from too much weight, swinging the bar, or a hand position the wrists and elbows do not tolerate.
The usual complaints are wrist and forearm discomfort and pain at the front or inner side of the elbow, typically after heavy loads, sudden jumps in volume or dropping into the bottom of each rep. The wide grip also turns the upper arms slightly outward, which some lifters feel at the front of the shoulder. Swinging the bar and leaning back moves the stress to the lower back.
Warm up with a light set, keep the torso still and lower the bar under control until the arms are straight, without letting the elbows snap into lockout. If the outer bends bother your wrists, elbows or shoulders, move your hands to the inner bends or switch to the Dumbbell Hammer Curl, which keeps the forearms neutral. If you cannot stop swinging, the EZ Bar Preacher Curl braces the upper arms and takes the back out of the lift.
Stop the set if you feel sharp pain at the elbow or wrist, or pain that builds rep by rep. A pop at the front of the elbow, sudden weakness turning the palm up, bruising or a new bulge in the upper arm needs prompt medical assessment.
Frequently Asked Questions
- Q: Can I use a straight bar instead of an EZ bar?
Yes. A study of trained men curling 65% of their max found no difference in biceps or brachioradialis activity between an EZ bar and a straight bar, so the choice mostly comes down to wrist and elbow comfort. The straight-bar version is the Barbell Curl (Wide Grip).
- Q: Does a wide grip target the inner head of the biceps?
Not in any proven way. The idea that a wide grip shifts work to the short (inner) head is common gym advice rather than an established fact, and both heads work hard in any strict curl. Choose between this and the EZ Bar Curl (Close Grip) by how each feels on your wrists and elbows, or rotate them for variety.
- Q: Is this variation better than a regular EZ bar curl?
No, it is a variation rather than an upgrade on the EZ Bar Curl. Moving the hands to the outer bends changes how the bar sits in your hands and how wide the forearms travel, which some lifters find more comfortable.
- Q: How wide should my grip be?
Use the outermost angled sections of the EZ bar to keep a wide but controlled grip. If that width strains your wrists, elbows or shoulders, move your hands to the inner bends.
- Q: Should I straighten my arms fully at the bottom?
Yes, lower until your elbows are straight so the biceps works through its full range, but do it under control rather than letting the bar drop and snap the elbows into lockout. If full extension under load bothers the front of your elbow, stop just short of it and lighten the weight.
