P90X or Insanity?!

they are both very different.

p90x is primarly strength training with cardio on the side.

insanity is hiit cardio but using body weight training.

They are both very different.

If you are looking to done, then go p90x.

If you want endurance, insanity.

btw why can't you do a hybrid of both?

As already mentioned, P90X focuses more on resistance training and Insanity focuses on endurance.

I've tried both, and quit for different reasons. They both work, but differently. I'm a big believer in building muscle to lose weight, rather than relying too much on cardio (although I try to do as much cardio as I can, for health reasons rather than weight loss). For that reason I like P90X better. The problem I found with P90X is that the exercises are very long (the Yoga routine is 90 minutes), and I started to get very bored, which is why I ended up switching over to Insanity.

Insanity is not boring for a second. The exercises are much shorter, and the intensity is amazing (I don't like working out unless I really push myself). However, the results I saw on my body were minimal, although my endurance shot through the roof. I wasn't following the Insanity nutrition guide to the letter, which is probably the reason. Then, a little over a week into the second half of Insanity, my back and my knees just gave up.

I'm sure you can see great results from Insanity if you follow the nutrition guide to the letter, but that seems a bit difficult to me (at least I found the recipes in it a bit unappetizing, for the most part). Also, and this is the big one, if you have even the slightest doubt that your joints can stand up to it, avoid it like the plague. It's extremely high impact, and the risk of injury is much greater than with P90X.

Now, I just started a new home fitness program called Rushfit, that seems to combine the best of both worlds (at least so far - I'm less than a week into it). It's an MMA workout routine, presented by MMA champion George St. Pierre, and it focuses on functional fitness. There's some resistance training (you'll need some dumbells - not too heavy), but it's incorporated into functional movement, as opposed to isolating muscles and doing reps, as in P90X. So far it's been very low impact (my knees are still a big problem for me), but it's way more intense than P90X. It's not as cardio heavy as Insanity, but I still find myself on the floor in a puddle of sweat after each workout. The best part, for me, is that it allows you to pick your own cardio workouts. So if you like Insanity and that sort of plyo focus, you could do that as well. Personally, I like to get out of the house, so I go swimming on my cardio days (and hope to go running as soon as my knee is better).

I don't know if I'm allowed to post links on this forum, so I won't, but you should just Google Rushfit and check out some reviews and things. Maybe that'll fit the bill.
