About this exercise

A standing rotational mobility drill where the arms swing behind the body in a wide arc, driving thoracic and lumbar rotation. It loosens the spine, obliques, and posterior shoulder girdle, making it an effective warm-up or mobility exercise.

How to Perform

  • Stand with feet shoulder-width apart, knees slightly bent, arms relaxed at your sides
  • Begin a smooth rotation to one side, allowing both arms to swing freely behind your body in a wide arc
  • Let the momentum carry your arms fully behind you as your torso rotates, keeping your hips relatively stable
  • Allow the arms to swing back to the starting position and then rotate to the opposite side
  • Continue alternating sides in a fluid, controlled swinging motion
  • Keep your spine tall and avoid rounding the lower back
