P90X has been a staple workout routine in everyone’s minds for over a decade now, with slightly different iterations coming out from time to time. The reason it’s been stuck on our minds is that it seems to work. We all know someone who’s used it and had some semblance of results. Tony Horton’s latest version, P90X3 takes the system to a more condensed path – just thirty minutes per day. Muscle confusion made up the original system and now muscle acceleration is the main concept of this version and reviews seem to suggest it works well too.
