Britney’s Killer Abs Are Back

Here is a new tour rehearsal photo posted on her Web site today and girl is looking fine.

Us Weekly says she’s lost 20 pounds these past few months thanks to cardio and strength training workouts 3 times a week in addition to all of her dance rehearsals.

According to the article in Us Weekly:

“It’s a nonstop workout,” Bally Total Fitness trainer Steven Boggs, who has worked with Spears, told Us of the routine, which includes moves like shoulder presses and jump squats.

She has also revamped her diet, opting for a 1,100- to 1,200-calorie-a-day meal-delivery plan from Sunfare consisting of three meals (breakfast burritos, barbeque chicken salad and turkey burgers) and two snacks (think cheese and nuts).

“I have had to work hard at getting [my body] back to where it used to be,” she said in January’s Glamour. “I used to be obsessed with working out … But I can’t get motivated right now because I’m so focused on my music.”

Her world tour, The Circus kicks off March 3rd in her home state of Louisiana.
