"A crash workout is not the best way to get in shape. Eating well and exercising daily over a long period is a much healthier &amp;#x2013; and easier &amp;#x2013; approach to getting a body you can live with. But if it&amp;apos;s a matter of vanity, not long-term well-being, you can turn your body around fast. &amp;quot;Three weeks may seem last minute,&amp;quot; says Ron Mathews, a Hollywood trainer who specializes in high-intensity circuit routines and who designed this 21-day workout for us. &amp;quot;But you just need to maximize caloric output and minimize calorie input while activating as many muscles as possible.&amp;quot;Simple. Grueling. Effective. Here&amp;apos;s your plan."^^<http://www.w3.org/2001/XMLSchema#string>
