Equipment

Setup

  1. Stand with feet shoulder-width apart and knees slightly bent.
  2. Reach both arms high overhead and rotate your torso toward the right side.
  3. Extend your hips and rise onto the balls of your feet to create a long, powerful line.

How to do it

  1. Explosively 'slam' your arms down and across your body toward your left hip while pivoting your right foot inward.
  2. Exhale forcefully during the downward 'slam' phase and hinge slightly at the hips to absorb the movement.
  3. Immediately reverse the motion to reach back up to the left side to begin the next rep on the opposite side.
  4. Maintain a fast, rhythmic tempo, alternating sides with each repetition.

Form checklist

  • Pivot the trailing foot to allow the hips to rotate fully and protect the knee.
  • Keep your core braced and your spine neutral throughout the entire rotation.
  • Use your lats and obliques to drive the arms down, rather than just using shoulder strength.
  • Ensure your knees track in line with your toes during the pivot and slam.

Pro tips

  • Visualize throwing a heavy weight into the ground to increase the intent and muscle recruitment of the movement.
  • Focus on a sharp, 'snapping' contraction of the obliques at the bottom of the slam for maximum core engagement.

Make it harder

  • Increase the speed and explosiveness of the downward phase to maximize power output.
  • Incorporate a small jump as you reach overhead to add a plyometric element to the exercise.
