Setup

  1. Stand facing a power rack with feet in a staggered or shoulder-width stance.
  2. Place your non-working hand firmly on a rack upright or crossmember at hip-to-waist height.
  3. Hinge at the hips until your torso is nearly parallel to the floor, maintaining a flat back.
  4. Grip the dumbbell with your working hand using a neutral grip, letting it hang at full extension.

How to do it

  1. Exhale and pull the dumbbell toward your hip, driving your elbow back and upward while keeping it close to your side.
  2. Squeeze your shoulder blade toward your spine at the top of the movement for a full contraction.
  3. Inhale and slowly lower the dumbbell back to the starting position, feeling a deep stretch in the lat.
  4. Complete all reps on one side before switching to the other.

Form checklist

  • Keep your spine neutral from head to hips; do not round your lower back.
  • Avoid rotating your torso to 'cheat' the weight up; keep shoulders square to the floor.
  • Ensure the movement is driven by the elbow rather than just pulling with the hand.
  • Maintain a stable base by keeping your weight evenly distributed through your feet.

Pro tips

  • Focus on the 'elbow-to-hip' cue to maximize lat engagement and minimize bicep involvement.
  • Initiate the movement by retracting the scapula (shoulder blade) slightly before the arm begins to move.
  • At the bottom of the rep, allow the weight to pull your shoulder blade forward slightly to get a maximum stretch on the lats.

Make it harder

  • Incorporate a 2-second isometric hold at the peak of the contraction to increase time under tension.
  • Use a 'dead-stop' variation by resting the dumbbell on the floor between reps to eliminate momentum.
