How to Do Seated Open-up and Under Swing on a Chair

  1. 1
    Setup

    Sit tall on a chair with your feet flat on the floor, hip-width apart, ensuring your spine is neutral and shoulders are relaxed.

  2. 2
    Setup

    Extend both arms straight out in front of your chest, palms facing each other, keeping them parallel to the floor.

  3. 3

    Inhale deeply as you sweep one arm out to the side, opening your chest and rotating your upper torso to follow the hand, keeping the other arm extended forward.

  4. 4

    Exhale as you bring the open arm back to the front, then swing it under the stationary arm, reaching across your body while gently rounding your upper back and rotating.

  5. 5

    Return the swinging arm to the starting extended position in front of you, maintaining a controlled motion.

  6. 6

    Alternate arms, performing the open-up and under swing on the opposite side, ensuring smooth transitions and controlled breathing.

Tips

  • Focus on thoracic rotation: Initiate the "open-up" movement from your upper back (thoracic spine) rather than just moving your arm, to maximize mobility benefits.
  • Coordinate with breath: Inhale as you open your chest to facilitate expansion, and exhale as you swing under to deepen the rotation and gentle flexion.
  • Keep hips stable: Maintain your hips firmly planted on the chair throughout the movement to isolate the rotation to your upper body and prevent compensatory swaying.
  • Smooth, controlled motion: Avoid jerky movements; perform each phase of the swing with fluidity and control to protect your joints and enhance mobility safely.

Common Mistakes

  • ×Rushing the movement: Performing the swings too quickly diminishes the mobility benefits; focus on slow, controlled movements to engage the target muscles and improve range of motion.
  • ×Moving the lower body: Allowing your hips to lift or shift off the chair reduces the effectiveness of the thoracic rotation; keep your glutes anchored to isolate the movement to your upper spine.
  • ×Holding your breath: Failing to coordinate breathing with the movement can restrict range of motion; inhale during the "open-up" and exhale during the "under swing" to facilitate deeper movement.
