How to do it

1. Lie on your back on the floor with your arms extended out to the sides to form a T shape.
2. Place your bent legs on top of an exercise ball.
3. Lower your bent knees to one side, keeping your torso and arms flat on the floor.
4. Then bring your knees back to the center and lower them to the opposite side. Repeat the movement for the desired number of repetitions.

Form tips

• Keep your shoulders flat on the floor to maximize the stretch in your spine and obliques.
• Move slowly and with control to avoid straining your back.
• Breathe deeply and steadily, exhaling as you lower your knees to the side and inhaling as you bring them back to the center.
