Close Grip Barbell Curl

A bicep isolation exercise using a narrow grip on the barbell to emphasize the outer, long head of the biceps. Bringing the hands inside shoulder width biases the part of the biceps that builds visible peak, making this the go-to barbell curl variation for that goal. It behaves like a standard barbell curl in every other respect, so the two swap into programs interchangeably.

How to Do the Close Grip Barbell Curl

  1. Grip a barbell underhand with your hands just inside shoulder width.
  2. Stand tall with elbows pinned to your sides and the bar at your thighs.
  3. Curl the bar up toward your shoulders without letting the elbows drift forward.
  4. Squeeze the biceps hard at the top for a beat.
  5. Lower over two to three seconds to fully straight arms.
  6. Keep your wrists straight and your torso still throughout.

Do This

Form Cues

  • Set the hands just inside shoulder width and keep the elbows pinned.
  • Curl without letting the bar drift away from the body.
  • Lower over two to three seconds.
  • If your wrists complain at this grip width, move to the EZ bar version rather than pushing through.

Avoid This

Common Mistakes

  • Swinging the hips to start the rep.
  • Letting the elbows travel forward at the top.
  • Gripping so narrow that the wrists take the strain.
  • Creeping the grip narrower over time, which strains the wrists without adding anything for the biceps.
