4. Cooper Wellness Program at Cooper Aerobics Center, Dallas

Guiding light
Don't be fooled by the serene woodland setting complete with duck pond. Cooper is a get-serious program for long-term healthy living, complete with a 40,000 square foot state-of-the-art fitness facility. Based on a complete fitness/medical assessment or (optional) thorough medical evaluation, a team of physicians, nutritionists and exercise technologists prescribes a fitness plan that's a perfect fit.

The staff's guiding light is Kenneth H. Cooper, M.D., M.P.H., the "Father of Aerobics" himself. Count on cooking classes and lectures on things healthy -- including Motivation & Goal Setting, Managing Stress and Understanding Antioxidants -- plus exercise sessions applying state-of-the art equipment and techniques. After sweating the books and gym, opt for a massage, contouring seaweed wrap, facial or pedicure at the center's Mediterranean-style Day Spa. Then there's that lighted tennis court! You'll earn your rest at the on-site Guest Lodge, a colonnaded mansion featuring private balconies.
