Engaging in brief, sporadic bouts of vigorous-intensity physical activity (VILPA) lasting 1-2 minutes during daily life significantly reduces all-cause, cardiovascular, and cancer mortality in non-exercisers, with effects comparable to structured vigorous exercise.
You do not need to join a gym or set aside large blocks of time for exercise to significantly lower your risk of death from heart disease or cancer. Look for opportunities in your daily routine to move vigorously for just 1-2 minutes at a time. Examples include climbing stairs quickly, walking very fast to catch a bus, or moving briskly between tasks. Doing this 3 times a day (totaling about 4-5 minutes) provides substantial health benefits comparable to structured exercise.
VILPA in nonexercisers appears to elicit similar effects to VPA in exercisers, suggesting that VILPA may be a suitable physical activity target, especially in people not able or willing to exercise.
