Instructions
Sit on top of a swiss ball near a wall. Walk your feet out and place them flat against the wall with your knees bent. Place your hands by your ears with your elbows pointing out wide.
Bracing your core, lower your body down until your lower back touches the curve of the ball. Raise yourself back up brining your torso close to your bent knees. Repeat for the programmed amount of repetitions.
Tips
To ensure you have the right size swiss ball, when you sit on top of the ball, with your knees bent and feet flat on the floor, your legs should form approximately a 90 degree angle.
To decrease the difficulty of this exercise you can place your arms across your chest.
