Having just turned 65, I was looking for something to help me maintain my strength and mobility which I know will slip away if I do not put some conscience effort into it. This DVD is perfect. I feel confident that her instructions and movements are safe as well as productive. Mirabai is pleasant and easy to follow. I especially like the rhythm, which for me makes it easier to keep going. It is not difficult to do the workout, yet I feel really good afterwards and I have already noticed an improvement in my posture. I have purchased some ankle weights and when I am able to do the enire leg routine with the weights on, I will move on to her strength training level 2. Thank you Mirabai.
