- For this variation, you will need a partner to assist the position of the Swiss ball.
- Lie on your tummy and have the Swiss ball placed over your tail bone and gluteals.
- From here, bend both knees so that your ankles are pressing against the ball and your knees at roughly a 90 degree angle.
- From this position alternate lifting each ankle up and down into the ball.
- This should be performed quickly and for the duration prescribed by your physiotherapist.
