| I use an exercise ball but just started to do it. My exercise ball came with instructions and examples. There are some exercises that I do on the ball that aren't with the instructions. I can photocopy the instructions for you if you would like or scan them and send them to you in an email. One of the things I do is sit on the ball and walk myself out so that my knees are at right angles on the floor and my back is on the ball. Then I put my hands behind my head and do mini sit ups. This helps the abdominals. One other is to sit on the ball and then balance and raise a leg one at a time and hold the leg up for a count of 10. These two exercises I didn't see on the instructions. Trying to raise my two legs at the same time is almost impossible for me at least. I'm still a klutz with the ball but each day gets a bit better. |
