1 - Kneel down in front of the ball and place your hands on the floor, slightly wider than shoulder-width apart. Extend your legs straight out behind you, resting your shins on the top of the stability ball.
2 - Engage your core muscles to create stability and maintain a straight line from your head to your heels. This is your starting position.
3 - Begin by bending your knees and pulling the stability ball toward your chest. As you do this, use your abdominal muscles to lift your hips slightly off the ground.
4 - At the top of the movement, your knees should be tucked in close to your chest, and your back should be rounded slightly. Contract your abdominal muscles as you hold this position for a moment.
5 - Slowly extend your legs back out behind you, returning to the starting position with your shins resting on the ball and your body in a straight line.
6 - Repeat the knee tuck movement for the desired number of repetitions. Focus on controlled movements and engaging your core throughout.
