Hi Cody, Yes, you can find Sit and Be Fit video demos here: https://www.youtube.com/user/SitandBeFitTVSHOW

Can we see a video demo?

Hi Debra,
We recommend a 9-12 inch ball. They are inexpensive and can be found (especially this time of year) in bins at many grocery or general merchandise stores. We no longer sell balls but when we did we purchased them from http://www.fitball.com/FitBALL-Mini-Ball-9-Inflatable-Exercise-Ball/productinfo/FBMINI/#.V4aciPkrJQI. These balls are a bit more expensive and need to be blown up. The advantage of this type of ball is that the material it’s made with is slightly tacky and easier to grip than the slick-surfaced balls typically found in stores. Hope this helps! Wishing you the very best in health and happiness!
