Duff appears on the cover of the December 2014 issue of Health magazine. She talks about being too skinny as a teenager, still loving her ex, and losing her baby weight.
I lost my baby weight from boxing, and I have this awesome trainer, Gabe. I was already there, but I definitely shed, like, 10 more pounds from doing two-a-days for two or three weeks, an hour each session=. I live in a cul-de-sac, but I have a big hill, so I would run the hill, then box in my cul-de-sac.
