Having recently graduated from Jillian Michael's 30 Day Shred, which I loved, I was looking for something else challenging but not boring! I achieved AMAZING results from the Shred and recommended it to many people. I read many reviews before buying "No More Trouble Zones" and most of them were right on!The exercises are mostly different from the Shred so you won't get bored and it has a little bit of a lower key feel to it. I thought maybe I wouldn't feel much soreness as I am in better shape because of "Shredding" all summer but that wasn't true!Jillian's exercises once again work to deliver her "big promises" that she will change your body! I am really glad I invested in another one of her videos!
