are you doing the same old workouts
all the time? Like, are Mondays always the same, Tuesdays, etc.? Mix it up. And, *gasp* even skip a day or two. That's right, I said SKIP A DAY!!! Remember, be very careful what you eat that day (calories in/calories burned still matter!). I hate to tell this in public, but I missed workouts for 2 weeks over Christmas when I went to FL. I gained 0.0 lbs, plus coming back and getting back into the routine jumped started my weight-loss again.
