Undated (WXOW) - Exercise can lengthen your life, even if you're overweight or obese.
They found that regular, moderate-intensity exercise can boost life expectancy even with an unhealthy B-M-I, or body mass index.
On the flip side, the doctors say healthy-weight people who don't exercise had about three fewer years of life.
