Setup

  1. Stand in an athletic stance with feet wider than shoulder-width and knees slightly bent.
  2. Clasp your hands together and bring them to your trailing hip, loading approximately 60% of your weight onto the back leg.
  3. Pivot your back foot slightly inward and engage your core to prepare for the rotation.

How to do it

  1. Pivot your back foot and drive your hips forward, rotating your torso explosively across your body.
  2. Swing your arms in a slight upward arc toward the opposite shoulder, exhaling sharply as you reach the peak of the rotation.
  3. Control the deceleration at the end of the movement, then inhale as you reset to the starting position with a controlled tempo.
  4. Complete all repetitions on one side before switching to the other to ensure consistent power output.

Form checklist

  • Ensure the back heel lifts and the foot pivots fully to protect the knee and allow hip rotation.
  • Keep your head and gaze following the path of the swing to maintain neutral spinal alignment.
  • Maintain a slight bend in the elbows throughout the movement to engage the lats and deltoids.
  • Keep your core braced and chest up to avoid rounding the lower back during the follow-through.

Pro tips

  • Initiate the movement from the floor; the power should travel from your calves and glutes through your obliques to your arms.
  • Focus on a hard 'stop' at the end of the swing to train your core's ability to decelerate force, which is vital for injury prevention.

Make it harder

  • Increase the speed of the rotation while maintaining a perfect 'stick' at the end of the range of motion.
  • Incorporate a lateral shuffle or a step into the swing to increase the momentum and demand on the stabilizing muscles.
