Any increase in physical activity reduces mortality risk of physically inactive patients

According to the British of General Practice, Physically inactive primary care patients reduced their risk of mortality by increasing physical activity, even in doses below recommended levels. Greater reduction was achieved through meeting physical activity recommendations or adopting levels of physical activity higher than those recommended.

So, exercise, as mentioned on this running vs weights post, is an essencial tool for your health.
