The exercise that you mention... is that a new thing for you, or something you've been doing awhile? Have you recently increased the intensity or duration of your workouts or added more resistance in strength training?
Are you following WeightWatchers POINTS, or SparkPeople's calorie ranges?
I'm very new to maintenance myself, but in WeightWatchers, if you do have a gain, you subtract a point for every pound gained. First week of maintenance I was on 29 points but had a 1.6 lb. gain so I subtracted 2 points and this week am on 27 points per day. I hear it takes some "fiddling around" to find what works for your body.
But if you've recently kicked it up a notch with exercise, your muscles will retain water for a few weeks due to the increased workload, often causing a temporary gain. You can read about this in the "ask the expert" section under FITNESS or just ask and I'll post the link.
Energy and persistence conquer all things.
