No time for gym? According to World Health Organization, physical activity does not necessarily means running a marathon or playing competitive sports. It can be walking children to school or taking a brisk stroll in the park. Studies show that increasing daily walking steps is associated with a decline in the body fats, reduced waist girth and improved resting heart rate. Keep your daily steps no fewer than 7,500, as it helps avoid tummy fat accumulation. Use stairs but not elevator, alight two bus stops early, it all adds up to the steps taken per day.
