You would think people would know this by now, but I guess these sorts of studies are seeing if "lowering the standards" for exercise still has enough of a beneficial effect. If we could get away with it, I think most of us would eat delicious foods and not exercise. I really wish we could have "exercise in a pill".

I think this drum still needs to be banged, either more often or in a different way.

This might sound ridiculous, but some people even equate calls for exercise with fat-shaming. I've seen complaints like that posted in internal FAANG newsgroups as a response to events encouraging people to do exercise.

This new research tells us that you actually don’t need to properly exercise, using up a lot of your time to see a positive effect on mortality rates. A few short activity bursts will do. Chances are that more people will be willing to fit this into their daily routine. Wearable devices can gamify this for you.

And it may act as a motivator. How many people end up being literally petrified by the prospect of having to spend a few hours exercising every week? And rather not exercise at all.

On the bottom line, it may help improve the health of a cohort that does not currently exercise at all.

I think they are more to determine a set of specific guidelines that make it easier to recommend to people.

Saying, "Eat good food and exercise more" is very general, whereas "Get 10 minutes of intense exercise per day" or something like that is more measurable and actionable, especially with the use of wearables...
