"I've always been active throughout my life, so working out makes me feel good and look fit," says Decker.
And she doesn't let a busy schedule get in the way. "When I'm traveling, I love going for a jog - it lets me sightsee and get a boost of energy. If the weather isn't cooperating, I'll pop in my Elle Make Better Series workout DVD and do some yoga or cardio!" Decker says.
As for her beauty routine, Decker likes to keep it simple. "Make sure to have your beauty basics: lip balm, mascara, and Q-tips," she says.
