I recommend this program to everyone! I feel so much better and have less or no pain when I’m unable to workout because of life I remember what I can do ( not workout) little helpful movements My doctor just recommended I continue with program. I see how helpful and fun it is. You actually miss working out when you’ve been away. This program can be done with dvd, phone, iPad and computer. I understand you can transfer to tv. Customer is superb. I love it. Your body will love you. I would say a lot of work and thought has gone into this. Everything is clearly explained. I suggest you try. I believe there’s a few free.
