Query: Not for beginners and simply awful drum music

I was disappointed with this video. There is no emphasis on form or Pilates' philosophy. The women in the video are super flexible and are able to contort their bodies in ways that would be impossible for 99.99% of the population. It is fascinating to see, but difficult to follow, since they don't show you what the movements would look like when done by someone with normal flexibility. I would imagine that trying to copy these women (ie, laying your shin flat across your chest) could lead to injury. Also, the music, which consisted of 4 drum beats repeated over and over and over, was like an excruciating torture. Whatever were they thinking of?
