Jillian Michaels' 20-Minute Workout

Tone your entire body with the Biggest Loser trainer Jillian Michaels' super-efficient 20-minute workout routine.

Jillian Michaels is exactly what you expect in person: gorgeous, sculpted (check out those arms!), full of energy, and straight-talking. But what you wouldn't expect The Biggest Loser trainer to say this: "I don't like to exercise." Huh? "Let's face it, there are plenty of other things we'd all rather be doing," she explains. "I know how good I'm going to feel when I'm finished, so I make myself do it—but I like to get in and get out. I want my workout routines to be quick and high-intensity. In fact, you should be able to sculpt your entire body in just five moves." To prove it, Jillian Michaels has pulled five exercises from her new DVD, Ripped in 30, to help you sculpt sexy, lean, fierce muscles in one month. Your goal: Sweat it out (it takes only 20 minutes), high-five yourself for a job well done, then go enjoy the rest of your day!
