[EX Q]: Naader was my first yoga teacher. When we moved out of state, this video was my link to the best yoga routine I have ever done. I tried other instructors and other videos, but Naader's approach is the best -- a balanced mix of yoga instruction and inspiration. I have shared this tape with many friends (who then bought their own copy!) and they all agree that Naader's instructions are easy to follow and the pace is slow enough that beginners can figure out what is going on before the next pose; but not so slow that experienced students get bored. Furthermore, since he is doing the poses along with the student, he knows just when to offer that extra word of encouragement when you are about to give up! I find something new to ponder each time I listen to this tape. Naader's words are from the heart and they reach out to touch your heart as well as your body. Buy this tape and use it!!
[EX A]: Positive

[EX Q]: This cd is horrible!!! I thought that it might sound a little like there first, but it just sounded weird. It was so bad that when i put it in my cd player, i started bleeding from my ears. Skip this cd for gods sake and by something better like a rake or a loaf of bread.
