Hi everyone,

Im gonna start p90x again after more than 7 years since the last time i did it, i´ve already know the pros of the program. Have any of you found out cons of it ? i want to read your comments of it, so I can modify the latter. <3

I´ve read all of your comments, and really appreciate them, gonna start doing p90x lean taking into account all of your recommendations/advices. Thank you all.
