I have done Bikini Boot Camp and perhaps I am not the best person to write about it, since I am in PT for a torn trap. (I can do anything but overhead weighted work and downward facing dog.) It does move, but there is no special award for keeping up with them. Form is more important than speed. I did not preview and I usually do, so I felt a little behind at times. I like to be prepared. I did not hold the 2# weights, because I did not know what to expect and because of my shoulder. I feel like I will get better in time.
I like that you are not repped to death. (This is why I can't do Tonique even though I love Sylvia.) I really liked the toning segment at the end--again, you're not doing 673 reps. The cardio component is typical kick boxing moves, but it kept me engaged.
You will not like this if you don't like non-stop talking in Denise Austin-type voices. The music is very quiet and used for back ground, it doesn't drive the workout. I do wish the warm up/cool down were a touch longer.
Like I said, it moves, but you don't have to move at lightning speed. Make it your own.
