One Minute of Hard Exercise Can Boost Your Heart Health — Here’s How
If you feel like you never have enough time to exercise, here’s some good news: a powerful new study suggests that even one minute of vigorous activity can deliver surprisingly big benefits for your heart.
Yes — just 60 seconds.
A team of researchers has found that one minute of vigorous-intensity exercise offers the same health benefits as eight minutes of moderate activity or up to 156 minutes of light exercise like casual walking. So if you’re short on time, those quick bursts of effort may be your new best friend.
What Counts as Vigorous Exercise?
You don’t need a gym membership or fancy equipment. Vigorous exercise simply means anything that gets your heart pumping fast and leaves you a little breathless. This includes:
- Brisk walking or fast stair climbing
- Jogging or running
- Fast cycling
- Dancing
- HIIT workouts
- Jumping jacks or skipping
- Heavy gardening or household tasks
A good rule of thumb: If you can only speak a few words before needing a breath, you’re in the vigorous zone.
If you’re using a fitness tracker, look for 80–100% of your max heart rate (which is 220 minus your age).
The Study Behind the Claim
Published in Nature Communications, the study tracked 73,485 adults—average age 61—who wore activity monitors for a full week.
Here’s what they found:
- Vigorous activity was nearly six times more effective for heart health compared to walking.
- Short bursts of movement, even under one minute, improved the body’s ability to fight off diseases like heart disease, type 2 diabetes, stroke, and some cancers.
- These results challenge the commonly used guideline that 1 minute of vigorous exercise equals 2 minutes of moderate exercise.
Researchers also highlighted that these findings are especially helpful for adults who are busy, time-poor, or at higher health risk.
Even everyday tasks—carrying heavy bags, climbing stairs, or walking uphill—count when done with intensity.
A Second Study Echoes the Same Results
Another study from the University of Sydney looked at 3,293 adults who didn’t follow any formal workout routine. They found that just 1.1 minutes of vigorous movement per day reduced the risk of early death by 38% over six years.
These “micro-workouts” throughout the day included:
- Playing actively with kids
- Walking quickly uphill
- Carrying heavy items
Small efforts. Big impact.
So… Should You Stop Walking?
Absolutely not.
Walking is still one of the best, most accessible exercises for all ages. It helps with:
- Muscle strength
- Mobility and flexibility
- Better sleep
- Lower stress
- Improved blood pressure
A long-term study even found that women who averaged 4,400 steps per day had a significantly lower mortality rate than those who took 2,700 steps — and benefits increased up to about 7,500 steps.
The takeaway? Combine both: regular walking for overall wellness + short bursts of vigorous activity for heart health.
Conclusion
If you’ve been struggling to fit exercise into your day, this research is empowering. You don’t need an hour. You don’t even need 10 minutes. Sometimes, just 60 seconds of effort is enough to strengthen your heart and add years to your life.
If you’re new to exercise, it’s always wise to consult your doctor or a certified trainer to find a routine that suits your health needs.
