Kelly wants to tone up `Military style`

London: Pop singer Kelly Clarkson is spearheading for a weight loss after she went for a fitness regime used by police academies and the military. The singer`s fluctuating weight has attracted a string of comments after she was seen sporting a fuller figure in recent months, Contactmusic reported.

The `American Idol` winner is delighted after choosing CrossFit, a cardio and strength training program, because it gives her so much more energy when she`s performing. "I love it! It`s like boot camp. You never work out more than 35 minutes, but it`s so intense. You do things like box jumps, then 50 sit-ups, then 50 squats and then running, the American Idol winner says. "Me, my backup singers and my hair-and-make-up girl do it together. And in my shows, everybody has noticed. They`re like, `Dude, you have 100 percent more energy!", she adds. The `Breakaway` hitmaker insists she`s never felt uncomfortable about her waistline despite critics criticising her size at times. "My happy weight changes. Sometimes I eat more, sometimes I play more. I`ll be different sizes all the time, Clarkson says. Bureau Report
