We learned last year that Lauren Conrad loves kickboxing, but it looks like she's upped the ante and according to In Touch is now doing what her trainer calls the Body Box. Sounds vaguely sinister, but Jarret Del Bene, LC's trainer, says the boxing circuit is a full-body, high-intensity workout. Because the combos are always changing, the Body Box is also a boredom buster, which is good since the Hills star does the workout two to four times a week. The workout mixes punching and kickboxing moves with squats and other conditioning exercises.
Del Bene said LC follows a healthy diet, but she is limiting her caloric intake to 1,200 to 1,500 calories a day, portioned out into five or six small meals. While that is not dangerously low — an adult requires about 1,200 calories daily before the metabolism slows down as if there is a threat of starvation — I think I would feel hungry all the time if I ate like that every day, especially if I was exercising intensely.
