If you've been checking out the fitness scene lately, you've probably heard the buzz on Pilates. Although it sounds like one of those $5 coffee drinks they sell at Starbucks, it is in fact a highly sophisticated exercise form. Is this the sort of thing you should try?

What is it? It's an exercise technique invented for injured dancers about a century ago by ex-carpenter and gymnast Joseph Pilates. There are two ways to practice Pilates (pronounced pih-LAH-tees). You can take a group class on a mat where you'll do specialized calisthenics exercises, or you can take private lessons on a series of specially designed machines with such exotic names as the Cadillac and the Reformer. Whether you take the mat class or use the machines, all Pilates moves are designed to work your powerhouse muscles -- abs, lower back, thighs, and buttocks -- and to teach you proper alignment so you move more freely and gracefully.

Why we love it: Pilates incorporates so much of what today's exercisers need. It increases strength, flexibility and endurance and improves posture, alignment, coordination and balance -- all without building bulky muscles. Nothing is forced or repetitive; you emphasize correct form rather than going for the burn.

Drawbacks: It's expensive. Private lessons will set you back $40 to $200 a session. By comparison, mat classes are a bargain, running $12 to $25 a class, depending on the instructor or the part of the country you're in. Many gyms offer classes to members at no additional charge and private instruction at a discount. If you like to master things quickly, this may not be the workout for you. Like dance, yoga and martial arts, learning Pilates is a long-term, evolutionary process.
