Being a couch potato. Not exercising. A sedentary or inactive lifestyle. You have probably heard of all of these phrases, and they mean the same thing: a lifestyle with a lot of sitting and lying down, with very little to no exercise.
In the United States and around the world, people are spending more and more time doing sedentary activities. During our leisure time, we are often sitting: while using a computer or other device, watching TV, or playing video games. Many of our jobs have become more sedentary, with long days sitting at a desk. And the way most of us get around involves sitting – in cars, on buses, and on trains.
