T, Y, I's are fantastic for your lower back, hips and abs.  You can do these in three different positions that will work different areas of you back.  The “T” position is with your arms out to your sides, the “Y” position is with your arms in the shape of a “Y” in front of you, and the “I” position is with your arms straight forward in front of you.  You can choose one arm position or alternate through them all!

1. Lie face down on the ball with your arms stretched forward.
2. Lift both of your arms, chest and abs as high as you can.  Inhale with this motion.
3. Exhale and lower slowly.
4. Repeat
5. Inhale up, exhale down.
