"This has been a tough year," says Jillian Michaels, 42. That's because she's been doing "a Herculean amount" of work juggling her latest DVD, 10-Minute Body Transformation ($5; amazon.com); her newest book, Yeah Baby!: The Modern Mama's Guide to Mastering Pregnancy, Having a Healthy Baby, and Bouncing Back Better Than Ever ($16; amazon.com), and her live show, An Evening with Jillian, which tours this spring. On top of that, she and her fiancée, Heidi Rhoades, are busy raising daughter Lukensia, 6, and son Phoenix, 4.
"There's one thing I noticed about my kids," says Jillian when we meet for coffee in Malibu, Calif. She's wearing ripped jeans, flip-flops, and a Black Sabbath T-shirt with sleeves rolled at the shoulders, revealing those fierce arms. When Heidi took the kids away for a week, Jillian dived so deeply into work that she was fried by the time they came home. "And that's when I thought, 'Maybe, Jillian, as much as you moan about how hard it is, your kids balance you out.'"
