i'm on my 6th week of insanity and i've lost 14-15lbs. i'm really strict with my diet maybe only going over a day or two every other week on caloric intake. Here's a bland answer that everybody is different and you might just develop at a different rate. If the scale isn't moving but you feel like your body comp is changing that's ok. focus on how your clothes fit and how you feel. If you're still unhappy really look at your diet and make sure that is on par.
I know using this app/program has kept me accountable

I am middle of week two, not a single lb off but. Keep sneaking a peek at the tape measure as I look smaller in the mirror can't wait to see the final result, I'm hooked. I do find I could cope with an extra set tho, can't wait for month two as they are longer circuits. Can't wait to feel skinny, the best feeling is I feel like I have had a bum lift

I lost about 9lbs total over 63 days, but had no loss until about week 4.

While 9lbs isn't a lot my pictures look like 20lbs lost.

I had a friend do it several months ago and she didn't lose a single pound but lost 6 dress sizes. I would take losing 6 dress sizes over a few pounds I'm hoping to see some movement on the scale but more than that I want my size 10s to fit me again!

I'm currently in the 2nd week of month 2 and have dropped 13 lbs so far. What I've noticed is drastic changes in my thighs and *kitten* more so than anywhere else. My lower half is significantly leaner and my thigh muscles have really firmed up. I've taken pics every 2 weeks but since they're from the waist up, I don't think they really do my progress justice since most of changes have been from the waist down. I'm now able to fit into pants that I haven't been able to wear in over 3 years due to how much my lower half has slimmed down (for a dude, I usually have quite the bubble butt).

5 years ago when I did P90X, I noticed that the changes first occurred on my lower half back then as well. Once my legs/*kitten* really slimmed down and firmed up, then drastic changes started happening to my upper half (face, gut, chest). I'm hoping that will be the case again with Insanity this time.

I've also noticed that during Month 2 it is harder for me to get my heart rate up to where it was during the Month 1 workouts. I'm definitely working harder in Month 2 but I can tell that my body and heart are in better shape than in Month 1. My legs muscles are what make me need a break now instead of a thumping heart rate and being out of breath. I'm starting to feel like a BEAST!!!

I bought a size 4 slim fitting skirt. I'm using it as my goal, cause i always weigh heavy and gain muscle fast. So when its fitting without being skin tight, Ill know I'm on the right track
