This workout is part of the Masters series, intended as an intermediary between P90 and P90X. This workout is a cardio circuit containing two rounds, each consisting of the same set of a dozen or so exercises each done for one minute each. During the minute, Tony increases the intensity every twenty seconds (i.e. you go from easy to slightly harder to hard-core). Two background exercisers (Dreya and a guy whose name I don't remember) assist Tony and he banters with them throughout.

I really enjoyed this workout. It is very well chaptered, so if there is an exercise you don't like, you can skip it (I hate the wacky jacks!) Also, if you are like me and only have half an hour to work out in the morning, you can easily stop after the first round and get in a solid routine. Or, you could skip some of the exercises and get it down to 45 minutes.

The minute goes by very quickly, and since you are only doing the most intense version for twenty seconds, it is easy to push yourself and really go for it. I found this workout was a good intensity for me. Overall, I really enjoyed it and am a little sorry I left this sitting on my shelf for so long before I gave it a try!
