"Twenty Minutes of Standing" Workout
For almost a decade, Gretchen Johnson's popular column in The New York Times, PhysEd, has been focused on the science of health and fitness. Her book, "The First 20 Minutes: Surprising Science Reveals How We Can Exercise Better, Train Smarter, Live Longer," a distillation of her work, will certainly surprise those who believe that people need to exercise strenuously to stay healthy. Johnson's research shows that just doing something, even standing for 20 minutes a day, will help you maintain good health and prolong life. For those who question how that can be true and what it means in terms of losing weight, keep reading. Just wish that the PhysEd teachers of the past had read the book!
