According to the book “The First 20 Minutes: Surprising Science Reveals How We Can Exercise Better, Train Smarter, Live Longer,” 20 minutes a day is all you need to get fit. Throughout the book, author Gretchen Reynolds, explores the concept that fitness doesn’t occur by working out for 30 minutes, then sitting the rest of the day. Being constantly on the move is what leads to better fitness and a longer life. According to Reynolds, staying seated for long periods of time at a desk, on the couch or in the car can lead to multiple health problems. She recommends standing up and walking at least once an hour and exercising in short bursts throughout the day. Reynolds is a health and fitness writer who is regularly published in The New York Times and The New York Times Magazine.
