If you often feel sick or sore backs due to incorrect sitting or sitting too long, just overcome with simple yoga movements. Sit on floor with legs folded and feet together. On the in breath, gently pull your knee closer to the face.
This movement is very easy and can be performed in front of the TV. Another advantage of this movement is that it can prevent bladder problems such as cystitis (bladder infection) because it helps stimulate the kidneys to excrete the bacteria that are not necessary from within the body.
