Dumbbell High Curl

  • Intermediate
  • Isolation
  • Rep-based
  • Shoulders
  • Upper arms

The Dumbbell High Curl, also known as the Crucifix Curl, targets the biceps in a highly shortened position to emphasize the 'peak' of the muscle. By keeping the arms elevated, it minimizes shoulder involvement and forces the biceps to work through a unique angle of resistance.

Setup

  1. Stand with feet shoulder-width apart, holding a dumbbell in each hand with an underhand grip.
  2. Raise your arms out to your sides until they are parallel to the floor, forming a 'T' shape with your body.
  3. Turn your palms to face upward and keep a slight bend in your elbows to maintain tension.

How to do it

  1. While keeping your upper arms perfectly still and parallel to the floor, curl the dumbbells toward your ears.
  2. Exhale as you flex your biceps, squeezing hard at the point of maximum contraction near your head.
  3. Inhale as you slowly extend your arms back to the starting 'T' position using a controlled 3-second eccentric phase.
  4. Maintain a stable torso and avoid letting your elbows drop toward your ribs throughout the set.

Form checklist

  • Keep elbows aligned with your shoulders; do not let them sag downward.
  • Maintain a proud chest and keep your shoulder blades retracted and depressed.
  • Avoid swinging the torso or using momentum to bring the weights inward.
  • Ensure your wrists remain neutral or slightly supinated (palms up) rather than curling toward the forearms.

Pro tips

  • Focus on driving your pinky fingers toward your temples at the top of the movement to maximize bicep supination.
  • Imagine you are performing a 'front double-bicep' bodybuilding pose to enhance the mind-muscle connection.

Make it harder

  • Incorporate a 2-second isometric hold at the peak of the contraction on every rep.
  • Perform the exercise unilaterally (one arm at a time) to increase the demand on your core and stabilizers.
