What is the difference between P90x and Insanity, view a short video here.
P90X2 is definitely for athletes. More functional with the concepts of Core Performance book with regards to Mobility and Stability.
It is NOT really any more difficult then P90X. It is, however, a LOT more core strength and functional balance.
If you or someone you know has back issues, 90% of which are caused be a week core, then THIS is the program that will solve those problems.
Good video explaining the difference between P90X and P90X2.
P90X2 focuses much more on stability, balance, and body awareness than any other exercise program in a manner that makes it appear deceptively easier than, in fact, it really is.
Phase 1 is not as extreme as P90X and I believe more valuable to get your body ready for more extreme workouts. Plus with the functionality it is specific to athlete preparation which again Steve Edwards has written a few blogs about the different phases for endurance athletes, "inside training for the outdoor athlete" it is. Most folks who purchase BB programs are not endurance athletes
Avoiding injury and gaining longevity while adding some explosiveness are what I'm interested in.
