From front to back, Jessica Biel has got it going on, but how does she maintain her bombshell bod?

From diet to exercise, the 30-year-old star, who covers the August 2012 issue of InStyle, reveals all of the secrets to her sensational physique – and Breaking Celebrity News has the details.

A hard body doesn’t come without hard work – sometimes even late night workouts she admits – but Biel keeps motivated by mixing up her workouts.

“Some days I’ll sprint on the treadmill; other days I’ll hike with the dogs. I also fit in yoga classes and some swimming.”

“My trainer, Jason Walsh, works with athletes, so we do a lot of football drills, like pulling big sleds and waving heavy ropes,” she adds. "It’s intense cardiovascular training but really fun.”
