Exercise guide

Dumbbell Seated Drag Curl

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

The Seated Drag Curl is a specialized bicep isolation movement that emphasizes the long head of the biceps by pulling the elbows back, minimizing front deltoid involvement while engaging the posterior deltoids. This variation creates intense peak contraction by keeping the weight close to the body's center of mass.

Setup

  1. Sit upright on the edge of a flat bench with your feet planted firmly on the floor.
  2. Hold a dumbbell in each hand using a supinated (palms forward) grip.
  3. Let your arms hang fully extended at your sides, ensuring your shoulders are retracted and chest is proud.
  4. Position the dumbbells so they are lightly touching the sides of your thighs.

How to do it

  1. Exhale and curl the dumbbells upward by flexing the elbows while simultaneously driving your elbows straight back behind your torso.
  2. Keep the dumbbells in constant contact with, or very close to, your ribcage as they move vertically toward your mid-chest.
  3. Squeeze your biceps hard at the top of the movement where the elbows are at their furthest point back.
  4. Inhale and slowly lower the weights back down along the same vertical path to the starting position using a controlled 3-second eccentric.

Form checklist

  • Keep the dumbbells 'dragging' against your torso throughout the entire range of motion.
  • Ensure your elbows move backward, not outward, as you curl.
  • Maintain a perfectly upright torso; do not lean forward or use momentum to lift the weight.
  • Keep your wrists straight and firm to ensure the tension stays on the biceps.

Pro tips

  • Focus on the 'pinch' in your posterior deltoids as you drive the elbows back to stabilize the shoulder joint.
  • To maximize the peak contraction, try to turn your pinkies toward your shoulders at the very top of the movement.
  • Think of the movement as a vertical pull rather than a traditional arc-style curl.

Make it harder

  • Pause for 2 seconds at the peak of the contraction to maximize muscle fiber recruitment.
  • Perform the exercise unilaterally (one arm at a time) to increase the demand on your core stabilizers.
