Update 12/13/2010: In response to the comments by two of my readers, apparently I was wrong in my assessment of P90X in regard to time. Both of them said that I was too nice, as the workouts are actually longer than I thought they were. So, my updated grade of P90X in lieu of this new information is C-.
This is the second of 3 installments discussing the efficacy (or lack thereof) of the P90X program. To read Part 1, The Absolute Intensity Argument, click
HERE. This purpose of this post will be to evaluate P90X in terms of the construct discussed in Unit 2 of
The Theory of Fat Loss, the limiting factor theory.
Note: One of the comments on my previous post suggested that it is impossible to evaluate P90X without reviewing the nutrition system with it as well. While I completely agree that you can never out train a poor diet, the purpose of these posts is not to discuss nutrition. Even the poorest exercise programs out there can look fantastic if a good diet is followed. I am simply critiquing an exercise program as it stands by itself.
The Theory equips people with an evaluation system to objectively look at any training regimen, so I am merely providing you with an example of how it can be done.
Note 2: Let's not get accusatory in my comments section! It takes a lot of courage to post things non-anonymously, especially training results. I just recently posted a guest entry on this... the "
your a skinny b*****" post. What matters is that people continue to make progress and that we help and support them, not tell them they are too thin or whatever. Even if somebody is technically "underweight," I don't see a problem with it if they are still improving their numbers in the gym. Now, if a person starts regressing or getting physically ill, then there is a problem, but being light doesn't mean unhealthy. I must say though that it does support my point about P90X not being a hypertrophy program.
Okay, without further ado...
