I love this DVD! My doctor kept telling me to start walking but I live alone and wasn't comfortable walking by myself. Plus in the winter it is too cold outside to walk. I also started noticing my balance is not as good as it use to be and I knew that the amount of sitting I was doing was not good for me. My friend recently bought this DVD and showed it to me and this I must say is exactly what I needed. I have been doing the DVD for a few weeks now and I feel so much better. I have more energy, feel like my balance is improving and the strength training I am convinced is definitely making me stronger. I also love how Nancy leads the class and it is so wonderful to look at beautiful Lake Tahoe throughout the entire program. Thank-you for making this great program available!
