I bought this DVD about a month back and decided to follow the rules and work out religiously. I started the 30 day shred about a month back and the results have been phenomenal. After a week into the work out I noticed dynamic changes in my body. I was toned, had more strength in just a weeks time. Seeing these results I have continued it so far and am extremely happy with my purchase. I am not the kind of person who purchases work our DVDS but I would highly recommend this. I must say the 20 minute work outs are very convenient. A must say for anyone who needs to shed weight or need some toning.
