30 pounds is totally doable... When I did my yo yo dieting last year, I found once I got over the initial shock of working out, I wanted to do it more when I was stressed. Use the stress to motivate you to go to the gym or work out at home!! I felt like I was stressed out when I didnt get to do some kind of workout. Dont look at wedding stress as a bad thing, use it as a good thing. I love to think when I am on the tredmill... If you run into an issue and your fiance doesnt know what to do, go work out and think about it and see if you can come up with the solution. I love the stess work outs... You want to do more!!
