Looks like it could be a good read but it's paginated to shit ...
Also, this is misleading (under P90X):
>Requires significant investment into purchasing fitness equipment to perform workouts (e.g., dumbbells, pull-up bars, yoga blocks, all sold by Beachbody)
>• Likewise, Beachbody ties additional revenue streams to their products—in this case, an extensive supplement line.
This is all the equipment you really need. $47. At least that's all I use and it works just fine. And the supplements are also not mandatory.
I just started P90X (did the first workout this morning). This is pretty much all you need (in addition to a mat and a towel). Read the reviews too, it's basically the all-in-one for P90X if you don't want to buy directly from Beach Body (much more expensive due to superfluous equipment).
Edit: I have Bowflex Dumbbells but even those can take a beat to change the weights on. The resistance bands are the easiest when momentum is important.
