Hi there.. I was in the same boat as you two years ago. My mom got me a gym membership etc, spent over 2 thousand on personal trainer... and NOTHING. Just like those late night commercials, I was sitting and eating some crap and watching shopping channel. I decided to order one of the beachbody cds. Did the program (really had to motivate my self for 6 weeks, but I did it), and I lost only a few lbs, but 15 inches altogether. I was thrilled. I got another (different) cd, and did that one too. Another few pounds lost, and A LOT of inches. So I ordered another one! And got a puppy.
Two years later, I'm down 40lbs, and 7 pant sizes. It may not seem like a lot for 2 years, but I am so proud. I have 20lbs left till my Sept. 2011 wedding, and I hope I can do it. I have a basement dedicated to doing it. But if you don't have the space for exercise at home..... walk to the store, explore your neighbourhood. Now that Xmass is around the corner, use an excuse "I want to see the Xmass decorations in the hood" LOL... Just walking alone for 1 hr will burn off those extra calories.
I'm still stuck on having bad weeks - yes - weeks, not days... but I start feeling guilty and in my head, my ass is growning... so I get back on the horse. When you live through the first few weeks, and lose a couple of inches/pounds - you'll start missing the exercise after skipping a few days. Always imagine what you want to look like on yor wedding days.
I'll tell you my honest secret. I have a friend who has a nice body (not perfect), but nice. When I exercise, I imagine two things: My wedding dress on me, and looking better then her )))))))))
