How to Do the Seated Corkscrew: Oblique Exercise Guide

Master the Seated Corkscrew to strengthen your obliques and core. Follow our expert step-by-step guide for better stability and rotational power.

How to Perform

  1. Sit on the floor with your knees bent and feet flat, then lean your torso back slightly until you feel your core engage.
  2. Place your hands behind your hips for support or extend them in front of you to increase the balance challenge.
  3. Lift your feet off the ground while keeping your shins parallel to the floor in a tabletop position.
  4. Rotate your knees and hips together toward one side while keeping your shoulders facing forward as much as possible.
  5. Reverse the movement to bring your knees back through the center and then rotate them to the opposite side.
  6. Focus on exhaling as you twist and inhaling as your legs return to the starting position.
  7. Maintain a tall spine throughout the set to prevent your lower back from rounding against the floor.

Common Mistakes

  • Rounding the lower back which transfers tension away from the abdominals
  • Using momentum to swing the legs rather than muscular control
  • Moving the shoulders excessively instead of rotating from the waist
  • Holding the breath throughout the repetition
