First and foremost, it's important to remember that muscle tissue is much denser than fat, so you can't let the scale dictate your motivation. Nonscale victories are much more important in the long run, because they can keep coming even if the scale is being stubborn. Things to concentrate on are: how your clothes fit; how your wind is improving; what you can lift; your energy levels and mood. Letting the scale decide for you is an invitation to failure.
