Kudos to 4 Seconds Workout and Our Hidden Sixpacks

Four seconds of high-intensity exertion repeated periodically throughout the day might counteract some of the unhealthy metabolic consequences of sitting for hours, according to a surprising and timely new study of the potentially large benefits of diminutive workouts.
The study relied on a specialized type of stationary bicycle that few of us will have available at home, but its implications remain broadly applicable and suggest that even a few minutes — or seconds — of exercise each day could help substantially to bolster our health.
For most of us, sitting is our default posture and was, even before the shelter-at-home edicts took effect across the globe. Epidemiological studies indicate that most American adults sit for a least 10 hours a day, a total that is likely to have risen now that many of us are home all day.
The health impacts of this inactivity can be considerable, with studies linking prolonged sitting to increased risks for heart disease, Type 2 diabetes and other metabolic disruptions. In particular, multiple hours of sitting can contribute to a later rise in the bloodstream of fatty acids, known as triglycerides, probably in part because muscles at rest produce less than contracting muscles do of a substance that breaks up triglycerides. High levels of triglycerides, in turn, are linked to an increased risk of heart disease and other metabolic problems
