What is Correct Posture?

Ideally, a correct posture means sitting with your back straight, chest up and out and your belly completely tucked in. Make sure you do not stiff yourself so hard that it becomes a strain for your muscles and bones. Also make sure that the chair you use for a long time is comfortable and gives support to your spine. Try to sit at a go without jerking your body. Likewise, try to stand in the same flow.
