People often think if they sit all day without moving that they can compensate by doing a few hours intensive exercise at the end of the day, but it doesn't work like that. It's creating a regular movement, changing posture throughout the day.
"We’re designing environments that are making people’s lives easier, where you can save time by taking the elevator over the stairs, or where you can pick up a phone to save yourself the trip to another room in the office. But at the same time, we’re eliminating the need to move. You can design the most ergonomic chair possible and mitigate pain at a desk, but it still doesn’t require the body to stabilize on its own or to change its position frequently. Our population is always on the lookout for the newest trend, and right now the standing desk is it. Though a step in the right direction, standing isn’t the solution to our increasingly sedentary lifestyles. Sitting is not the problem. It’s the amount of time we spend doing any one behavior that threatens the health of the body."
