I own about 7 or so work out videos. They all give me a good work out, but this video wins the prize for total body sweat! I typically do the Warm Up, Metabolic and Power train as my custom work out, and for a 35 minute work out I really feel it. Each exercise is only 1 minute long but the pace is fast and you end up working out your entire body. I have been working out steadily for about a month and a half and I still get my but kicked by this video. I highly recommend this work out program. And the "Its all about the reps" part is a great fast 15 minute work out if you don't have the time for a full 30. In a week or so I will brave adding all three parts as one long 45 minute hardcore work out but I just don't feel ready yet.
Lastly, I can contribute at least 5lbs so far to this video alone since I started using it two weeks ago. Well with a proper diet of course. I have lost more weight faster with this video then even with the P90 and all without the aches and pains that comes from the P90. I can not recommend this video enough, and I really hope they come out with a more advance version in a few months when I should be ready for it.
