4. You stay passive and do not move enough
Your might spend most of your time in your office doing boring filing. Then you return home, spend a few hours watching your favorite talk show or chatting to your buddies on Skype. This kind of lifestyle does not involve any physical activity. What you need is to remember to move around every 30-40 minutes. Stand while speaking on the phone, talk a walk before bedtime or simply do your domestic chores more often. When at work try and do stretching, watch your posture and do other small things that at first sight might seem useless. It does not matter what you do, just stay more active!
