Fitball Pull-In
Start in a plank position on the fitball. Keeping your arms straight and midsection firm, contract your abs and pull the ball in towards your chest. Then extend your legs and roll the ball back to starting position.
Note: This is a modified option for those of you who struggle with starting with the ball down towards your feet.
To make this exercise more difficult, then start with the fitball further down so your ankles are on the ball.
