Query: Shelved

I purchased this DVD for a friend who is beginning yoga. I have been practicing yoga and pilates for years using home video and DVD instructions. The instructor's movements were too quick and the vocal instructions were muffled and vague. I did not share this with my friend because I thought it would be discouraging for a beginner. Unfortunately, this one will be shelved.
