Go for a run pushing your kids in the stroller (even more cardiovascular benefit than just running by itself tbh). Do a bunch of squats at home while cradling your toddler (it becomes funtime for them, like they're on a mini rollercoaster ride). Take your kids for a hike, whether they're tiny and need to be brought along in a baby carrier or they can walk by themselves.
Basically, you can make it happen if you really want it to happen.
> 560 and 610 minutes a week of moderate to vigorous physical activity
I was always a little suspicious when they would say that you only need moderate exercise like walking because when you do vigorous exercise your blood vessels expand up to 3x diameter, keeping your arteries supple and elastic. You just don't get that by walking.
30%+ reduction from 10 hours a week of exercise sounds ideal, but 9% isn't nothing.
Honestly, only a hypochondriac or a narcissist would consider 10h/w acceptable. Everyone is too busy trying to stay alive.
The number only makes sense if you're a body-builder or an influencer who trades on appearance.
Jokes aside, 10 hours a week is quite something. Good that they mention that 2-3 hours is also already beneficial.
15 MET hours above 3 METs gain 70% of the possible benefits from cardio.
Not exactly contradictory results, but it makes this sound like bullshit.
I wonder if healthy diet also plays role in the outcome.
> In order to achieve substantial protection, classed as a greater than 30% risk reduction, between 560 and 610 minutes of moderate to vigorous exercise a week was needed.
So 30 minutes a day is still good, but more is better. Seems reasonable.
Also exercise doesn't mean planned / scheduled exercise, like going to the gym. Daily activities can count, like cycling to the train station for example. Which gets to one of my favorite hobby horses: increasing exercise at the population level is an urban design problem.
I wound up in a fairly walkable part of Calgary. But Calgary is not a super walkable or bikeable city. Transit here is at best ok, and winter gets very cold. There are some good bike paths but you have to be pretty determined to use them when it snows or it's -40 out.
I guess what I'm saying is urban design is super important, but geography has a say too. We don't all get to live in the relatively mild west coast weather.
While 560-610 minutes of moderate to vigorous physical activity certainly helps, I'd think these are individuals who are generally abstaining from smoking, will try to eat healthy at least moderately often and stay away from overconsumption of fast food, etc.
Basically, it sounds like there is a degree of correlation here between habits and outcomes that is being conflated with causation.
> Adults should aim to do between 560 and 610 minutes a week of moderate to vigorous physical activity to achieve a substantial reduction in the risk of heart attacks and stroke, suggest the findings of an observational study published online in the British Journal of Sports Medicine.
It is highly likely that healthier people exercise more (and the bedridden exercise way less). Also, who exercise more: people who care about their health in general, who don't overwork themselves, who have disposable time and income.
For example, an older person's walking pace is strongly correlated with their remaining life years. If we force these people to walk faster, they won't outrun death - we would very likely just increase their mortality.

Can we stop doing this please?
