I used this tape for 3 years to build strength. I watched it every morning from 5-20 mins at a time as I was getting over back pain and other problems. It got me in great shape to start taking classes. I have not been injured since. This tape is slow, easy to follow, brilliant in its line up of Asanas, and great for strengthening. I recommend it to EVERYONE who wants to start out yoga cheaply, by watching a video at home!
