Think about the position of your body by sitting all day.

By sitting all day, you’re not depending on your powerful lower body muscles to hold you up. This leads to muscle atrophy, which is the weakening of these muscles. Without strong leg and glute muscles to stabilize you, your body is at risk of injury. When you sit for several hours a day, your core is not engaged, your neck can be strained. The seated position puts huge stress on your back muscles, neck, and spine. It’s even worse if you slouch.

But remember: No matter how comfortable you get, your back still won’t like a long sitting session. Get up and move around for a minute or two every half hour to keep your spine in line.
