Taylor Swift is flexing her muscles in the new issue of Marie Claire magazine.

But her biceps, triceps and abs made no appearance.

Instead, the country megastar is showing her philanthropic strength in the pages of the mag, which has named her one of its “20 Women Changing the World.”

She once told Cody exclusively what drives her to put her money where her mouth is and donate to good causes.

"I think that if at the end of your life you're know with this legacy for being kind and nice to people and giving more than you take, that's a huge huge accomplishment," she says.

Marie Claire notes that since her career has skyrocketed, Taylor has given well over one million dollars to disaster-relief efforts and $4 million to create a music-education center at the Country Music Hall of Fame and Museum in Nashville.

Also appearing on the “20 Women Changing the World” list is Shakira, Jennifer Garner and former first daughter Chelsea Clinton.

Taylor is due to release her new album 1989 on Oct. 27.
