Start in a kneeling position facing away from a wall with a stability ball on the floor in front of you.
Lie face down onto the stability ball with it positioned under your upper torso.
Place your feet against the wall with your knees bent and your arms by your sides, palms facing downwards.
Maintain a neutral spine and engage your deep abdominal muscles throughout this exercise.
Simultaneously pinch your shoulder blades together and reach your arms into a 90/90 position as you push your feet into the wall, extending your knees until your body is in a straight line from head to heels.
The ball should now be positioned at your lower abdomen.
Return to the start position with control.
