Cardio? More like hard-io
560-610 minutes of exercise a week needed for substantial heart benefits
New heart advice says exercise way more — and the internet is absolutely not having it
TLDR: Researchers say major heart benefits may require around 10 hours of exercise a week, far above today’s 150-minute minimum. The community reaction was instant disbelief, with many arguing that this might be realistic for athletes but absurd for busy adults, parents, and anyone with a normal schedule.
A new study says the usual 150 minutes a week of exercise may only deliver a modest benefit for heart health — and that getting a much bigger drop in the risk of heart attack or stroke could take a jaw-dropping 560 to 610 minutes a week. Yes, that’s basically 10 hours, and the comment section reacted like it had just been assigned unpaid overtime by its own body. One reader summed up the new vibe perfectly: the old target was already a stretch, and now the goalposts have apparently sprinted away.
The biggest drama? Time. Parents, workers, and regular exhausted humans immediately piled in with variations of: who exactly has 90 minutes a day lying around? One commenter joked that if you spend that much of your life exercising, you might “get more lifespan not exercising,” which is the kind of dark math the internet loves. Another pointed out that even walking 5+ miles a day still doesn’t get them close enough, while someone else basically asked if researchers have ever met a two-income household with kids.
There was also a smaller, nerdier subplot: the study suggests people who are already less fit may need to do even more to get the same payoff, which readers saw as both brutally unfair and painfully believable. Researchers do note this was an observational study, so it doesn’t prove cause and effect. But online, the verdict was immediate: great news for elite cyclists, terrible news for everyone with a calendar.
Key Points
- •The observational study found that 560-610 minutes per week of moderate to vigorous physical activity was associated with a greater than 30% reduction in cardiovascular risk.
- •Current public health guidance of at least 150 minutes per week was associated with a more modest 8-9% reduction in cardiovascular risk across fitness levels.
- •The analysis used data from 17,088 UK Biobank participants, with wrist-based activity tracking and estimated VO2 max from cycle testing.
- •Lower-fitness individuals needed about 30-50 more minutes of weekly moderate to vigorous exercise than higher-fitness individuals to achieve similar cardiovascular benefits.
- •Researchers said the findings support current guidelines as a minimum standard but suggest future advice may need to be personalized by fitness level.
