Brachialis Narrow Pull-Ups

Body Part: Arms

Muscle: Biceps

Equipment: Pull-Up Bar

Brachialis Narrow Pull-Ups are pull-ups performed with a close grip to emphasize elbow flexion. The biceps and brachialis work hard to bend the arms, while the lats, brachioradialis, forearms, and upper back help pull the body toward the bar.

The narrow hand position changes the feel compared with a standard pull-up. It often increases arm involvement and can make the elbows travel close to the ribs. The movement still needs a strong shoulder position, active core, and controlled body line so the rep does not turn into a swing.

Set up by gripping the pull-up bar with the hands close together, hanging with the arms extended, and bracing the trunk. Pull the elbows down and back, lift until the chin reaches the bar or your clean range limit, then lower slowly to a full controlled hang. Use assistance if bodyweight reps are not yet consistent.

Use this exercise as an arm-focused pull-up variation, a bodyweight biceps and brachialis builder, or a progression from assisted close-grip pulling. Stop the set before grip failure causes slipping or shoulder position breaks down.

Instructions

• Grip a pull-up bar with your hands close together in a comfortable narrow position.
• Hang with your arms extended, shoulders active, and legs quiet beneath you.
• Brace your core so your body does not swing as you start the pull.
• Pull your elbows down toward your ribs while bending your arms.
• Lift your chest toward the bar until your chin reaches the bar or your clean range limit.
• Pause briefly at the top without craning your neck.
• Lower under control until the arms are extended again.
• Reset the hang before the next rep rather than bouncing from the bottom.

Tips & Tricks

• Use a band or assisted machine if narrow bodyweight reps shorten your range.
• Keep the grip narrow but not so cramped that the wrists or elbows hurt.
• Think elbows down first, then chest up toward the bar.
• Control the lowering phase to train the brachialis and biceps eccentrically.
• Keep the shoulders away from the ears at the top.
• Avoid kicking the legs to start the pull.
• Stop the set before grip failure causes loose, swinging reps.
• Use slow negatives if full reps are not available yet.

Frequently Asked Questions

What muscles do narrow pull-ups work?

They mainly work the biceps and brachialis, with help from the lats and forearms.

Are these harder than curls?

Yes for many people, because you are lifting your bodyweight instead of a handheld weight.

Can beginners do them?

Beginners can use a band, assisted machine, or slow negatives to build toward full reps.

Why are these called brachialis pull-ups?

The close-grip elbow-flexion demand emphasizes the brachialis along with the biceps.

How narrow should my grip be?

Use a close grip that lets the wrists and elbows feel comfortable. Extremely narrow is not required.

Should I swing to get my chin over the bar?

No. Use assistance or shorter clean reps instead of swinging.

What if my elbows hurt?

Widen the grip slightly, reduce volume, or use neutral-grip assisted pulls.

Are slow negatives useful?

Yes. Slow lowers are a good way to build strength for full narrow pull-ups.
