Doing Insanity...am I insane??!!??
 

I applaud you! I started P90X last summer and felt the same way- was I crazy? Just make sure you listen to your body. Take rest days if you need them, take more breaks at first during the videos if you need them. In my case, I pushed too hard too fast and got sick with a virus I couldn't get rid of (probably because I was exhausting myself working out harder than I was used to). I am now re-starting P90X but plan to work my way into it at my own pace and take rest-days as needed (I'll do yoga or something light on those days).

I did a few weeks of insanity with my sister, we were training together, but she got injured, so we switched to something else (moksha yoga) for a while. We're back to running now, and I'm doing some other DVDs. But I haven't forgotten about the Insanity program- I still want to do it. I'm traveling a lot the next 3 months so I'll probably wait until my travel schedule is clear before restarting.

I did 3 weeks, perfectly according to the schedule. The biggest problem I had with it was that my calves were killing me. It's a lot of plyometrics every day, make sure you have great shoes.

So, how was it? I was thinking about doing this program myself.
