I have recently purcheased the P90X workout DVD's. Has anybody here tried using it and does it really give you good results? I hear good things, but I know it's really hard for most people to stick with it. I'm sure it gets easier to stick with as time goes by, but I really dont want to commit 6 days a week to something that isnt going to give me results. Ansers, thoughts or comments would be helpful. Thanks.
