It’s the same mechanism that has been selling wonder diets for decades: Make it look novel and many people will flock to it.

RT, I agree, especially about the resistance routines.

I look at it this way: When you compare the production values of my videos and site to P90X, I simply can’t compete. So if you want a fully polished and sleek product, P90X certainly offers a perfect package.

Muscle confusion, afterburn effect…

But why are you talking about P90X now? Is it still in fad? I thought it’s was already forgotten.

I guess P90X has set an interesting standard. People would spend more than 100$ per month for fitness. Maybe 200$ is the limit. Could this be pushed any further?

I’m surprised there are people who’s willing to pay 180$ per month for not getting bored and getting new routines.

Wonder what word will be coined by next guru. And how much he/she will charge!

Let’s watch!

I’m confused how you can have a review of P90X without addressing any of the workouts specifically.

Awhile ago I did just that:

Evil, feel free to remove the link if you feel it’s inappropriate.

To sum it up, the cardio routines are interesting and challenging. If you have the money to spend it might be worth using those to add variety to your cardio. Not so fun jogging when there’s a blizzard outside.

The resistance routines frankly are a lot more complicated than needed, but will make your muscles grow. They appear to have been designed mainly as quasi-HIIT cardio workouts.

Muscle confusion is more a buzz word to help push sales; any routine needs to change every once in awhile (3-6 months) or you will adapt to it and stop seeing gains.
