Hilary Duff Heats Up May 2015 Cover of SHAPE Magazine

It looks like she made good use of her time out of the spotlight, because Hilary Duff is back and hotter than ever.

The 27-year-old “Cheaper By The Dozen” star is featured on the front of SHAPE magazine’s May 2015 issue, sporting a beautiful smile and some killer abs.

Of her new TV Land show “Younger,” Duff explains, “I embrace the mess. I had to be careful not to screw up in public as a child actor. So on my new show, Younger—which is written by Darren Star, who created Sex and the City—it’s really fun for me to play Kelsey, a 27-year-old book editor whose personal life is a hot mess. She always chooses the wrong guy, drinks way too much, and has to cover for herself the next morning.” Hilary also shares her fitness philosophy- “I don’t do auto-gym. I go three times a week and mix it up every time. I work out with weighted balls, battle ropes, and big rubber bands. I do this thing with a sledgehammer where I swing it and hit a rubber block, and it gets out all of my aggressions. Everyone is like, ‘Uh-oh, Hilary’s got the hammer—get out of the way!’”
