A back exercise targeting the spine, performed with stability ball.

Lie face down on a mat with your legs extended and your toes resting on top of the stability ball.
Place your hands on the ground, shoulder-width apart, and engage your core muscles.
Keeping your legs straight, slowly lift them off the ground, using your lower back and glutes to raise them as high as possible.
Pause for a moment at the top, then slowly lower your legs back down to the starting position.
Repeat for the desired number of repetitions.
