Just bought this DVD a couple weeks ago and watched it. Good exercises. I had just bought Lotte Berk DVD's as well, so I'm still on that series, but will return to this one. I liked that Lotte Berk had specific stretching exercises during and after each set of exercises (upper body, ABS, etc) and ended with stretches for lengthening the muscle. Although this one had the same type of exercises in many cases, I liked the individual stretches after each set with Lotte Berk...this and other DVD's always have some cool down, which normally involves stretching...still a good DVD, but it obviously didn't win my attention more than the Lotte Berk's DVD's did...you will have to evaluate what that says. I'm really enjoying the Lotte Berk DVD's and seeing some results. I have so many Exercise DVD's and none of them hurt you, but will you see the results...Aside from the heart, I want also to see the physical changes too. I can't say at this time if this will or will not produce results.
