I will start by saying this is my first online review of any product, ever. But I really like this video enough to want to share my opinion. I own a lot of workout DVDs such as several by The Firm, Mitch Gaylord Melt it Off, Jillian Michaels and some kettlebell workouts. This workout really is a great blend of challenging but doable. Each exercise is done for a max of one minute, so even when they are tough, when you know it is one minute, you can push through it. Brooke is not annoying at all. And those of you who do other videos know exactly what I mean by this. some instructors are just too annoying to listen to time and time again. She also demonstrates each move before it begins. This is one complaint I have about The Firm. I do wish the music was a little more upbeat, and have the moves go to the beat. And the total length is about an hour. It is tough to find a full hour, but you can do just certain parts of the workout if you are short on time. I have not been doing the video long enough to see results yet (2 weeks total, 2-3 times a week), but I have plenty of videos that I have tried and shelved after just a few times but this is one I will stick with as I do enjoy it, as much as exercise can be "enjoyed". I also I feel like this will produce some good results if I am consistent and watch my eating.
