They are different. Insanity relies solely on your body weight whereas P90X incorporates weights as well. I believe completing P90X helped me with Insanity. I was able to complete all of the exercises and go for the entire duration of the workouts; however, Insanity is still difficult. It is more cardio, plyo, non-stop movement than P90X; however, you need the breaks in P90X because you are asked to lift weights as well as using your body.
Heck, P90X is still challenging. I finished Insanity on Sunday, and this week I started P90X+, the maintenance schedule because I will be traveling on business. Well, yesterday called for Upper Plus followed by Ab Ripper X. Ab Ripper X was still challenging even after having completed P90X and Insanity. Insanity has also helped me with doing P90X+.
My physique changed more with P90X than with Insanity; however, that might just be because I started P90X first.
