Instead of sitting still, the human body is built to move, the evidence of that is hidden in the way how our body is structured. There are more than 360 joints in the body, as well as 700 skeletal muscles, which allow for fluid, easy movement. Our skin is elastic so it can adapt to our movements. Today, many people sit more often than they move. Sitting for a short time can be beneficial to our health, but long periods of sitting are detrimental. They slow down blood circulation and prevent nerve cells from receiving the benefits of movement.

Sitting up straight is another issue with a sedentary life style. It is difficult to get into the habit of sitting tall. You can have postural problems if you round forward when sitting. You can sit at a computer, in a car, or even on a couch.
