You need more than you think. At least that is what the data whispers if you listen closely.
The current standard is 150 minutes a week. Moderate-to-vigorous stuff. You know the drill.
But what if you doubled it? Or tripled it?
Researchers in China looked at UK Biobank data. 17,08 people. Roughly eight years of health tracking. A long time. They wanted to see where the curve bends.
Here is what they found:
Hitting that 150-minute mark dropped serious cardiovascular event risks by about 8 to 9%. Good. Solid. A nice buffer.
Now look at the outliers. Those people exercising three to four times the guideline amount.
Their risk dropped more than 30%.
That is a massive gap.
We are talking 9 to 10 hours a week. An intimidating number. Who has the time? Modern life moves fast, but this demands a lot. Still, the benefits scale up. Especially if you are starting out untrained. Less fit? You get even more from the extra effort.
The study authors ran with this. They released a press statement saying the current guidelines are too low.
Too low.
“Less fit individuals need to do more exercise get the same benefits,” the British Medical Journal noted.
Aiden Doherty at Oxford called it misleading. He wasn’t involved, but he read the fine print. He said the focus on 560-plus minutes a week is a bad message.
Why?
Because every step counts. That is the real takeaway.
Doherty argued that while high activity clearly helps, telling the public to train like athletes isn’t practical. It isn’t sensible.
“Clearly, there will be cardiovascular benefit… but this is not a sensible public high health message.”
The authors eventually agreed with Doherty. They backpedaled slightly. Or rather, clarified.
Most people aren’t hitting the current guideline. Let’s get that done first.
“The primary public health message remains straightforward: achieving 150 min week of MVPA delivers meaningful protection regardless of fitness.”
You do not need to live in the gym. Your heart will thank you for showing up at all.
The data was solid, though. 1,23 serious events tracked over those years. Heart attacks, strokes, failure, fibrillation.
Steefen Petersen at Queen Mary University called the study “large and well-conducted.” He liked that they used devices, not memories. People lie about their exercise. Phones do not.
“Using device-measured activity… increases confidence in observed dose-response relationships.”
There was a steep escalation.
Want 20% risk reduction? You need about 340-370 minutes weekly. That is more than double the baseline.
If you are not fit, the hill is steeper. You might need an extra 30 to 5 minutes a week just to get to that same 20% mark as someone in shape.
Hard truth.
Only 12% of the sample hit the 560-minute mark.
High reward, high barrier.
The authors called 150 minutes a “robust universal minimum.”
But can you do better?
Probably.
Should the world push for it right now?
Debatable.
Randomized controlled trials need to run their course. Until then, keep moving.
Don’t stop.
