I have them and really love the program.
The only issue I've had with it is me.
Each video is about 45-50 minutes, always interesting and always an AMAZING workout. 6 days per week and one rest day.
Very very hard but nothing impossible. (Everything is high intensity but in between there are some good recovery days and such)
If you would like to see the videos here are some links
(for the sake of not having to deal with watching 45 seconds of japanese commercials everytime you want to work out.. you may want to still buy the legal DVDs but here if you want an idea)

To those with bad knees or anything.. there is LOTS of jumping/running/bouncing/moving. Lots of squatting, lots of high intensity drills.
My advice? Make the videos work for you and KEEP YOUR FORM.
Even if it means pausing, taking a minute, checking a mirror and getting your form PERFECT. I see way too many people doing these videos and just flailling around.
Best advice everyone ever told me, which has helped me get as far in this program as I have.
It is a MAX INTENSITY WORKOUT.
It DEPENDS on your heartrate being back to normal before you jump into the next high intensity workout. If you need more than 10-15 seconds between to get back...then wait. It's better than you jumping back in and giving up.
Personally I'm very happy with it. I'm not the kind of person that will get to a gym (too far, too many excuses, don't want to pay for a monthly gym pass) so it works for me. I get my 45 minutes a day, no matter what.
All you need is a yoga mat and some shoes.
The results so far have been very good. I am losing fat and gaining muscle.
BUT
- I end up in a puddle of sweat every evening
- There are days when I hate the videos and feel like I am going to die
- There are mornings after this workout where I am sore.. everywhere.
- It's easy to not make the time, everyday, or put it off. I personally prefer to do it in the evenings.
-I have known people who have gotten great results but subsequently, haven't kept them/kept up with working out a bit each day.
