Overview
The trunk extension on the Swiss ball develops low back and glute strength. Performing this exercise with you feet against a wall will add support and make it easier to perform. Once you’ve mastered this exercise with your feet against a wall try it in an open space. By keeping you feet together you will recruit more of the core. As you extend your back you will feel the ball shift underneath you and this movement will require more muscles to stabilize your body.
Description
- Balance with your stomach on top of the stability ball, with your toes on the ground.
- Drape your torso over the ball and place your hands behind your ears.
- Starting with the head and upper back, lift your spine one segment at a time off the ball.
- Return slowly to the start position.
Mistakes
- Cocking the head back
- Dropping the head
