An anonymous reader writes: We've all heard exercise helps you live longer. But a new study goes one step further, finding that a sedentary lifestyle is worse for your health than smoking, diabetes and heart disease. Researchers retrospectively studied 122,007 patients who underwent exercise treadmill testing at Cleveland Clinic between January 1, 1991 and December 31, 2014 to measure all-cause mortality relating to the benefits of exercise and fitness. Those with the lowest exercise rate accounted for 12% of the participants. Dr. Wael Jaber, a cardiologist at the Cleveland Clinic and senior author of the study, said the other big revelation from the research is that fitness leads to longer life, with no limit to the benefit of aerobic exercise. Researchers have always been concerned that "ultra" exercisers might be at a higher risk of death, but the study found that not to be the case. "There is no level of exercise or fitness that exposes you to risk," he said. "We can see from the study that the ultra-fit still have lower mortality."
