"Days of Our Lives" actress Alison Sweeney has been synonymous with getting in shape and looking great ever since she started hosing "The Biggest Loser" six years ago. But for Shape magazine's May issue, she not only encourages others to look their best but takes center stage herself -- in a teeny bikini, no less.

In the interview, Sweeney talks about how a seemingly small change in diet prompted her drastic weight loss, which got her from a size 12 to a size 4: she cut back on sugar.

But it's not just a change in diet that keeps Sweeney's body looking this fit at 36. "She loves to hike, bike, swim, and ski," according to Shape.

Sweeney, described in the magazine as an "overachiever," has also done marathons, half-marathons and even a triathlon since she felt she needed to push herself further and harder.
