I bought this DVD a few years ago. As a teacher of yoga myself (British Wheel), being a mum of 3,wife, working and studying, I no longer have time to attend yoga classes as I did in the past. Although I practice and teach my own style of yoga, it is so nice to put on a DVD, just for myself at home and be guided through a practice. Some of these postures may be quite difficult to do and it may be an idea to read up on some of the postures to help you get into them and to find some alternative and/or modifications. But as it says in the DVD "just do the best you can". I have found this is one of the best complete practices on DVD that I have come across and I feel that I have come to know Sharon and David as I practice with them. I use it as often as I can and to me this DVD represents the whole beauty and meaning of yoga. As yoga is an 'experience' and not just about physical exercise, then this DVD is the best I have found in leading you towards this. Last year I also purchased their other DVD 'Power to the Peaceful Warrior', which is a little different,shorter and perhaps a little easier with great music. However I still prefer the 'Transform Yourself' DVD and always feel recharged, peaceful and strong after completing it. I would highly recommend buying it and to use it regularly.
