  3. Engage your core and fix your gaze on a stationary point in front of you for balance.

How to do it

  1. Inhale as you lift the ball toward one shoulder and begin circling it behind your head.
  2. Exhale as you bring the ball around the opposite shoulder and back down to the starting position at chest height.
  3. Maintain a slow, controlled tempo, ensuring the torso remains upright and still as the ball moves.
  4. Complete the set in one direction, then reverse the rotation before switching legs.

Form checklist

  • Keep the standing knee 'soft' and avoid locking it out.
  • Keep the head and neck neutral; do not duck your head as the ball passes behind.
  • Maintain a tight core to prevent the hips or shoulders from swaying.
  • Keep the ball close to your head throughout the entire circular path.

Pro tips

  • Focus on the transition behind the head to maximize shoulder mobility and upper back engagement.

Make it harder

  • Perform the exercise with your eyes closed to further challenge your proprioception and balance.
  • Stand on an unstable surface, such as a foam balance pad or a BOSU ball.
