It's easier for most people to stick with a workout regiment if one can maintain a set routine, but for someone like Black Eyed Peas first lady, Fergie, a routine isn't an option.
"I kind of go on a five pound fluctuation every year," Fergie admitted. "It's just either up or down a couple pounds. It's just usually how I live. I don't know if that's good for you but that's the way it is."
While on their current world tour, the entire group has been working with Fergie's trainer, fitness guru DB Donamatrix.
"It's a different type of trainer when a dude inspires you to watch what you eat and change your whole, like, way of life," Will.i.am raved. "I just eat fruit, soups and fish, and I've been doing that stuff for six months. [I] lost 30 pounds. I haven't been this weight since I was in the 12th grade."
The Black Eyed Peas gave an intimate performance in New York City on Monday at an MTV World Stage concert presented by the 21st Century Beetle, reminding Will.i.am of the time before the Peas started drawing the huge crowds they've become accustomed to.
"You know, we started out playing venues smaller than this," Will.i.am said. "One time we did this one gig and it was so many people that weren't there that we were able to take our food from our writer and pass out chips to people."
