Sit on the stability ball and walk your feet forward until the ball supports your lower back and hips, with knees bent at 90 degrees and feet flat. Place hands lightly behind your head or crossed over your chest.

1. Engage your core and exhale as you slowly curl your shoulders and upper back off the ball.
2. Flex your rib cage toward your hips, ensuring the movement originates from the spine.
3. Pause briefly at the peak contraction while maintaining constant core tension.
4. Inhale and slowly return your upper back to the starting position on the ball, maintaining control.
