Step by step
Instructions
- Lie face-up with your knees bent, feet flat about hip-width apart, and fingertips resting lightly beside your head.
- Brace your core, keep your pelvis steady, and maintain a small space between your chin and chest.
- Curl your head, shoulders, and upper back off the floor while rotating one shoulder toward the opposite knee.
- Pause briefly at the top and squeeze the obliques without pulling your head forward or allowing your hips to twist.
- Lower your upper body slowly to the mat, then repeat the controlled curling motion toward the other side.

Tips
- Initiate the rotation through your rib cage rather than driving the elbow across the body.
- Exhale as you curl and rotate, then inhale as you return to the floor.
- Keep both feet grounded and your pelvis stable so the obliques control the movement.
- Use a comfortable range of rotation and keep your neck relaxed throughout every repetition.

Common mistakes
- Pulling on the head or neck with the hands.
- Swinging the elbow across the body without rotating the torso under control.
- Allowing the feet or hips to shift during the repetition.
- Using momentum instead of slowly contracting the obliques.
- Lifting into a full sit-up and losing focused abdominal tension.
