Megan Fox is showing some skin! The 31-year-old bombshell shared a selfie on Instagram flaunting her lean figure in a sheer, black lacey bra.
The photo, which was shared without a caption, shows the Transformers actress from the lips down, giving us a glimpse at her curvy cleavage and flat tummy.
Fox has spoken about her food and fitness plans in the past, proving that a lot of hard work has gone into maintaining her svelte figure.
The mom of three told E! Online that she's a fan of intense circuit training.
"I exercise really hard twice a week," she said. "I got my ass kicked this morning before I came here. I do bursts of cardio with really heavy weights. Circuit training."
Her go-to circuit training includes crunches, knee-ups, lateral planks and Swiss ball exercises in short five-minute bursts. She then rests for 30 seconds and repeats.
Her quick, but regimented workouts are dictated by celeb trainer Harley Pasternak, who says he uses the same approach with Fox's workouts as he does with all his A-list clients.
"The workouts we do are like all of my other Five Factor workouts," Pasternak said. "They are five phases: a minimum five-minute cardio warmup, a lower body sculpting exercise, an upper body toning exercise, then an abdominal sculpting exercise and finally, a five-minute cool down."
If you thought Fox's workouts sound intense, just wait until you hear what she says about her eating plan.
"I cut out all bread and those sort of carbohydrates," she says. "No crackers, no pretzels, no chips. Nothing unhealthy. The worst thing I put in my body is coffee, once a day."
Fox never misses breakfast and generally eats two egg whites before she starts the day. For a snack, she munches on almonds, a great source of vitamin E, while following the general guidelines to a Paleo diet.
