Vigorous exercise is dramatically more efficient than moderate or light exercise for reducing all-cause, cardiovascular, and cancer mortality.

To achieve the same reduction in cardiovascular disease mortality as 1 minute of vigorous exercise, you need 8 minutes of moderate-intensity exercise or 200 minutes of light exercise.

“For every one minute of vigorous intensity exercise to reduce your death from cardiovascular disease, you had to do eight minutes of moderate intensity and 200 minutes of light exercise.”
