Hammer curl

The hammer curl lifts dumbbells with a neutral grip, palms facing each other, shifting more work onto the brachialis and forearms.

Why it earns a spot

The brachialis sits under the biceps, so building it makes the upper arm look thicker, and the neutral grip is gentler on the wrists.

How to do it

  1. Stand holding a dumbbell in each hand with your palms facing your thighs.
  2. Keep your elbows at your sides and your torso still.
  3. Curl the dumbbells up without rotating your wrists, as if holding hammers.
  4. Squeeze at the top, then lower slowly to full extension.
  5. Alternate arms, or curl both together for faster sets.

Common mistakes

  • Swinging the dumbbells up with your hips; keep your torso still.
  • Rotating the wrists toward a regular curl halfway up; hold the neutral grip.
  • Rushing the lowering phase; take two seconds down.

Add reps to 12, then move up to the next dumbbell. Pair them with barbell curls rather than replacing them.
