I started P90X on December 26, 2010 and completed it March 30, 2011. These are my before and after photos. The reason I started P90X was that I was feeling terrible emotionally and disconnected from my body and I knew something had to change. Also, a friend of mine who had completed the program alluded to it being pretty hard and wasn't sure I could do it (thems there fightin' words!). While the before and after pictures definitely show a difference in my physique, the thing I am focused on is the smile on my face in the after photo.
I'm not going to list all my before and after measurements, but they are decent. I dropped from a size 12/14 to a size 8. I "only" lost 7 pounds during the program. I say "only" because I am told that muscle weighs twice that of fat but takes up only 2/3 the space, which explains the big changes I have seen to my body with relatively little change on the scale. My energy level is much higher and I am generally dealing with stress better and feeling more positive about the world. Next up is the "Insanity" program - I am starting tomorrow! It's a 60 day program and I'll probably post the results here when I wrap that up in early June. Stay tuned!
