Query: What huge RIP OFF!!!!!!!!!!

90% of all the exercises are strictly yoga poses. I am throughly disgusted that I spent my good money on a BIG RIP OFF! 2/3 of the book is spent with Mr. Weisberg loving the view of his own words in print.Take my advice and go to the library and rent either books or videos of yoga for FREE.Mr. Weisberg cleverly renames all of the poses but I can guarantee you they are Yoga poses as I took yoga instructions for 3 months and attend weekly classes on a continuing basis. I showed his book to my Yoga teacher and he was thoroughly disgusted that this supposedly professional person would do such an unprofessional act all for the sake of book sales.
