Query: If you can buy only one yoga video -

you need to buy this one! Suzanne is an excellent instructor - explains movements well. This video is easy to follow - has four people working at different levels - and feels wonderful! I own it in VHS and bought the DVD version, since I'm probably wearing it out. I have been able to work at a level comfortable for me and have noticed a toning and firming.
