Fun, effective workout . After dealing with back pain and general weakness for months, I finally decided to get proactive about the problem and start doing a daily workout. I'd tried this DVD once before, but had no idea of the incredible effect it can have in a very short amount of time. After starting to use it daily just a few weeks ago, I already feel much more limber and energetic all day. My aching back has disappeared, my arms and legs are significantly stronger, and I feel more clear-headed and lucid all day. I can personally attest that the claims on the back of the case, that it will "give your body an active workout and help you develop inner peace and outer strength" are entirely true. I highly recommend this program. Be aware that it's pretty strenuous, and I often find myself sweating heavily by the end, but if you do it every day, and really put some effort into it, you'll feel and look better very quickly
