Stamina Pilates Level 2 DVDThis product works very well with the Stamina Products Aero Pilates Reformer I own. Marjolein Brugman is a good instructor. The only criticism I have is that sometimes (especially on level 2) she does not allow enough time for set up so I have to pause and rewind to keep up. I am planning on purchasing level 3 at some point as I already own levels 1 and 2.
