Yes, weight lifting can temporarily bring a halt to the scale (muscles retain water to heal). But you lose fat faster, burn calories, firm up and build muscle. The more muscle you have, the more calories you burn at rest, the more easy losing and maintaining weight becomes (hence why men lose weight faster and can eat more and maintain). So keep up the exercise and get a tape measure. It's great to see inches lost when that scale isn't moving like we want it to. It will eventually move though.
