Sitting too much is now listed with smoking and junk food as a bad habit that increases your risk of heart disease.
New Australian research shows that half-an-hour in the gym will not make up for the waist-expanding damage caused by spending the rest of the day sitting.
But the good news is that doing chores in the house or gently walking around the office while on the phone might be enough to keep you fit.
The study joins the growing body of evidence suggesting too much sitting might undo the benefits of exercise.
The study measured the intensity of physical activities in 168 subjects over seven days. It found that, regardless of how much exercise they did or their total sitting time, those who took more breaks from sitting had lower risk of thick waists and lower levels of blood lipids(脂肪).

Researchers behind the Stand Up Australia project have written to the Rudd Government requesting $3.5 million for a two-year study into the impact of long sitting time on health and productivity of workers. The study would also develop and test strategies for reducing sitting time on the job.
