Trim & toned in 1⁄2 the time

Forget “no pain, no gain!” With these clever moves, you’ll strain less and slim twice as fast, promises fitness-guru-to-the-stars Kristin McGee. Her secret: using a resistance band (available for about $8 in stores like Walmart and Target) to speed sculpting and melt fat without adding bulk. Here, she shares the 8-minute routine that her A-list clients (like Savannah Guthrie and Tina Fey) rely on to tone trouble spots in record time. Just repeat these moves four times per week and you can melt up to 10 pounds and 3 belly inches in as little as 21 days!
