Wow! You are doing great! You'll be in that bikini in no time! How often are you doing the stairmaster? You gave the time but not how often/days. Sounds like you up'd the crunches, that was going to be my suggestion for the extra belly fat. The only other suggestion I have is to maybe give yourself a break. You may not want to workout everyday. Workout every other day and break in between to give your muscles a break (especially those ab muscles). Then on your days you workout, they will be able to work stronger. Other than that...keep it up!! Congrats on the good work!! You go girl!
