Exercise Ball Back Extension With Knees Off Ground

AbdominalsStability BallBeginner
Lie face down on the exercise ball, with your hips and pelvis supported on the ball and your feet wide apart for stability. Place your hands behind your head or crossed over your chest. Keep your gaze down towards the floor. Engage your core muscles and lift both knees slightly off the ground. Maintain this position throughout the exercise. Begin the exercise by slowly lifting your upper body off the ball, extending your spine and lifting your chest towards the ceiling. Keep your neck in line with your spine and avoid arching your back excessively. Pause briefly at the top of the movement, then slowly lower your upper body back down towards the ball, returning to the starting position. Repeat the movement for the desired number of repetitions, maintaining control and focusing on engaging your back muscles throughout the exercise.
