I bought the Power90 program, but did not buy the supplements. I followed Weight Watcher points program, instead of doing the suggested diet (many of the foods they suggest you eat to 'carve your physique' were not things I'd eat!) I was lucky, had a great, motivated partner who was ready to do this every day with me.
We finished the first 90 days without missing a single day, either of us. I lost a total of 22 lbs, which I was disappointed with at first, until I realized that I had achieved something more valuable ... I had a WAIST for the first time in YEARS! I lost a total of 23" (7 of those inches were from my waist!) I had muscle tone and two cans out of a six pack on my abs!
Having been overweight for most of my life, and never in very good shape, I can't tell you had exciting this was, not to mention how it makes you feel like you should be a spokesperson for the program! I had more energy than ever before in my life and I was proud of what I achieved. This program also helps you with your posture because you find yourself throwing back your shoulders and standing proud.
Now, how have I done with maintaining these wonderful results?
After completing the first 90 days I suffered a work-related injury and wasn't allowed to exercise for almost a year. Gradually, the weight snuck back on.
However, I still have the waist, and I know the muscles I built up are there, simply buried under this layer of fat.
I am getting ready to begin the program again and because I know it works, it will provide me with additional motivation I am sure I will need, because I know I will have some pain in the beginning due to muscles that haven't been worked for almost a year now.
I wish you much success, and can offer you this advice: Do the measurements and take the pictures, even if, no, ESPECIALLY if, you don't want to! They will truly motivate you and keep you going during the times you want to quit. Best of luck!
