I am now on week three, day 16 of this crazy, amazing and insane (hence the name) workout program "INSANITY!".
I have done P90X and thought nothing could get tougher than that. Even running a half marathon does not compare to p90x. So when the women at my school I work at told me about "insanity" I thought it would be a cake walk.
Was I ever wrong.
The first day I did the workout, it looked like I had jumped in a swimming pool with my clothes on. And I walked like a duck because of sore muscles for about 3-4 days, even with taking protein supplements.
I am now on week 3. Do I still sweat like crazy? YES!! I haven't missed a day yet in this program (Except sundays, which you are supposed to take off anyways) and I can already tell a difference in my body. My muscles are tighter and I am getting stronger and my endurance is pretty awesome. It is a 60 day program and I plan on doing it a couple times through.
It's interval training-- has 13 dvds and they tell you which workouts to do on which days to maximize your results. Usually it starts off with what they call a "warm-up" which is usually about 12-13 minutes of pure hell, followed by a few minutes of crazy stretching, followed by the actual work out where my heart rate gets up to 190 for about 4 minutes, take a 30 second water break only to start another 4-5 min. interval training... this goes on for about another 20-25 minutes before a 3 minute cool down and stretching.
I am in L.O.V.E. with this program and highly recommend it. However, it is not something you should jump in and do-- you should have a pretty good work out routine going on prior to beginning this. I tell you what though, you will get hooked once you feel the endorphins kick in from such an incredible, totally exhausting work-out! There is a reason why it's called INSANITY-- its totally and complete Insane!
