That's borne out by the recent American Cancer Society research. While sitting time increased risk of early death, irrespective of exercise levels, both being physically inactive and spending too much time sitting was far worse, says ACS researcher Alpa Patel. "Women who were the least active and spent the most time sitting were 94 percent more likely to die early compared to women who were the most active and sat the least," she says. "For men there was a 48 percent increased risk." The bottom line, Church says: "A fitness program and movement throughout the day are both important—it's all good."
