A year and a half ago, I lost about 30 pounds. I've mainly kept it off, except for a little holiday pudge.

Now, I'm thinking about getting leaner and going below 140 pounds. I'm planning to be more careful about more food choices (less sugar) and to run more.

Rock on, sister.

Have you thought about adding weight training? It does wonders as far as getting leaner goes.

I've done a bit of weight training, but haven't really kept at it. I think you're right that I should include some. Any tips?

Yes, come hang out in the Weight Training forum.

And read, "The New Rules of Lifting for Women". Excellent new book about weight training.
