I've been doing Insanity since August of 2009, and I'm still loving it!! I can't think of anything I don't like about it.
I started off doing a full round (following the schedule), but adding in 2 days a week of running to keep up my running shape. It took me a little over 70 days to finish the round that way, but I really needed to keep running.
Ever since then, I pick-and-choose which video I'm in the mood for as a cross-training tool for my running. I think it's great and has definitely made me a stronger runner. My core is the best it's ever been, and I honestly don't ever do the actual abs dvds that came with the program. The other videos alone work the abs sufficiently.
I'm always recommending Insanity to other runners. It's such a good way to strengthen your whole body. And I love to do either of the Recovery dvds the day after a long run.
I love that you can do these DVDs anywhere, too. (I even did them in the campground bathroom over the winter a few times!)
The workout is no joke. Even if you're fit, you will find them pretty challenging. I still can't do all the push-ups!
There's a new set coming out soon called Insanity- The Asylum. It's supposed to be even harder!! I can't wait to try that out, too.
Good luck with it! I think you'll find it worth the money and good for those days when you need a day off from running.
