Now a days people spend most of their time sitting on  chairs in their offices or using Personal computers.sitting on chair puts great stress on our Spine and also it badly effects our Posture.
To much sitting can have following effects on our body
1) back pain due to stress on spine
2) shortening of spine  ,which make us look like shorter than our actual height
3)it can make us look fat
So if we correct our body posture then we can look slimer,taller and can avoid back pain.
There are lot of exercises that correct posture but they are tough and will take lot of time to do.
