Equipment

Setup

  1. Assume a half-kneeling position with your right knee on the floor and your left foot planted firmly in front, both knees at 90-degree angles.
  2. Hold a single dumbbell with both hands, gripping it by the ends (bell-grip) or with overlapping hands.
  3. Position the dumbbell on the outside of your right hip (the side with the knee down) with your torso slightly rotated toward the weight.
  4. Engage your core and squeeze the glute of your trailing leg to stabilize your pelvis.

How to do it

  1. Exhale as you lift the dumbbell diagonally across your body and upward toward your left shoulder in a smooth, sweeping arc.
  2. Continue the movement until the dumbbell is above head height and outside your left shoulder, keeping your arms nearly straight.
  3. Rotate your chest to follow the weight, but keep your hips and front knee facing forward throughout the movement.
  4. Inhale as you slowly lower the dumbbell back to the starting position at your right hip with a controlled 2-second tempo.

Form checklist

  • Keep your front knee tracked directly over your ankle; do not let it cave inward.
  • Maintain a tall, neutral spine and avoid arching or rounding your lower back.
  • Follow the dumbbell with your eyes to encourage natural thoracic rotation.
  • Ensure the movement comes from the torso and shoulders, not just the arms swinging the weight.

Pro tips

  • Focus on 'pulling' with your obliques to initiate the lift rather than relying solely on arm strength.
  • Maintain a slight bend in the elbows to keep the tension on the deltoids and protect the joint.
  • Imagine you are throwing the weight over your shoulder, but maintain total control at the peak of the movement.

Make it harder

  • Narrow your stance by bringing your front foot directly in line with your back knee to create a significant balance challenge.
  • Perform the upward phase explosively and the downward phase with a 4-second eccentric count to increase time under tension.
