Adherence
Engaging in leisure-time physical activity of moderate to vigorous intensity (0.1–3.74 MET-h/wk, equivalent to up to 75 minutes of brisk walking per week) is associated with a 1.8-year gain in life expectancy after age 40 compared to no leisure-time activity.
If you currently do no leisure-time exercise, start by aiming for just 75 minutes of brisk walking per week. This low threshold is associated with gaining 1.8 years of life expectancy after age 40 compared to being completely inactive. You do not need to exercise for hours to see significant longevity benefits; consistency at a low intensity is highly effective.
A physical activity level of 0.1–3.74 MET-h/wk, equivalent to brisk walking for up to 75 min/wk, was associated with a gain of 1.8 (95% CI: 1.6–2.0) y in life expectancy relative to no leisure time activity (0 MET-h/wk).
Why this rating
