In the longest study of its type, researchers conclude: ‘Low physical capacity is a greater risk for death than high blood
pressure or high cholesterol.’

“We found that low aerobic capacity was associated with increased rates of death. The association between exercise capacity and all-cause death was graded, with the strongest risk in the tertile with the lowest maximum aerobic capacity. The effect of aerobic capacity on risk of death was second only to smoking.”
