The image is too small to see that you really need their particular brand of foam roller in order to find these exercises very useful. Half the emphasis of the exercises was on the massage of the bumps, which I don't have on my standard dark gray roller. And I don't want to spend over $30 to buy yet another roller just so I can use this DVD! Not to mention, the price was way too high for the amount of content, even if I did have the right kind of roller. There are a few exercises but I could probably have been just as satisfied by downloading free videos from Youtube. What I really wanted was a complete core workout and this really is not it. I wish I could return it!
