P90X cd's - good/bad/effective?

Hi - my friend gave me copies of the P90X cd's. Just wondering how effective they were - what order - what system you followed?
Any input would be most appreciated! I am not sure if I'll use them now, but am curious...
thanks!!!

My 17 year old uses them . The results are amazing. It is a VERY intense workout though!

Hi there

My 28 year old niece and her friend were doing it for awhile. They loved it but as Yvonne said VERY intense

Take care

Thanks TNB and Joyce - it does sound pretty intense and who has the time to do 1-1.5 hours per day of workout? I don't. It sounded good, but I don't think it's for me...
cheers!

I did something similar called "Insanity Fitness" and they were very intensive for sure.  In fact, I had to stop doing them because I had sore knees and ankles all the time.  I was enjoying them though.  Maybe I'll try them again.  You've inspired me 

 Santiago,

I do a different program by Beach Body and love it.  I have a friend who lost 100lbs in 90 days using P90x's pre cursor program called Power 90 in home boot camp.  He has now moved on to P90x as the other one is to easy for him now.  He swears by it.  I have watched (Yes I said watched) some of the videos for P90x and they do look intense but if you start with a slightly easier program it should work out no problem.  I will be doing 4 more weeks of Slim in 6 then starting p90x.  I will let you know how it works out.  I credit my Beach Body tapes with the fact my arms are looking great and according to my kids I now look like a teen ager from behind.  I am 11.5 weeks out from surgery and FEEL toned even if in some spots I don't quite look it yet.  Will keep you updated or if you try it let me know how it goes.  My friend does the classic program.
