Sheila Cluffs Aerobic Body Contour

Aerobics have gained much popularity since Cluff, a pioneer in the fitness industry, began teaching ""Cardiovascular Dance'' in physical education classes in New York. Now owner of several California spas, she also proselytizes for exercise on her nationally syndicated ``Staying Fit'' television show. But her success as a teacher and entrepreneur does not rub off in this book, a loosely organized, illustrated assortment of sketchily explained exercises, fitness tips, recipes and motivational chatter. Her reach exceeds her grasp, and the exercise method advocatedlight weights and floor exercises for strength combined with low-impact aerobics for flexibility and cardiovascular health has been better conveyed elsewhere.
