A SPECIAL REPORT: AEROBICS

HEART HOEDOWN: The latest craze in the trendy world of aerobics is “Country Cardio,” created by Libby Franklin of Lake Forest. Franklin has inspired hundreds to sport cowboy boots along with workout garb. . . . Country Cardio puts country line dancing in an aerobic format, including a warm-up and a cool-down. . . . Franklin’s weekly classes at Sports Club Irvine started slowly but now have up to 50 students, and the club may add a second class.
