The Blackroll as described by the seller.
However, one would have the DVD can save. Nothing is explained to the exercises. It simply runs a video on the individual exercises and then you have to see how to cope.
I prefer when something is explained how the exercise is done correctly and what to watch.
The illustrated exercises on the enclosed map are not very meaningful.
For beginners, the DVD is not really suitable. It if you have ever attended a course at the physiotherapist is best.
