Japan's 30-Minute Walking Trick That Helps You Lose Weight Quicker

That's exactly what a group of Japanese researchers started exploring nearly two decades ago. And the technique they developed, now known as Interval Walking Training (IWT), may quietly be one of the most effective and accessible fitness routines you can adopt today.
The Method: Simple but Powerful
Developed by researchers at the Shinshu University Graduate School of Medicine in Matsumoto, Japan, this walking style isn't about slow strolls or punishing treks. It alternates between three minutes of fast walking and three minutes of slow walking, repeated for a total of 30 minutes.
'Fast" here means walking at a pace where talking becomes difficult. 'Slow" means walking at a comfortable, relaxed pace.
Do this four days a week, and within a few months, you may notice changes far beyond what 10,000 steps ever did for you.
Backed by Years of Research
This isn't just a trending idea on social media. According to The Washington Post, the technique was first tested in a 2007 study led by researchers Hiroshi Nose and Shizue Masuki. The trial ran for five months and compared two groups one that did interval walking, and one that just walked at a steady, moderate pace.
The results? The IWT group showed significantly lower blood pressure, stronger thigh muscles, and improved aerobic capacity. The control group saw no such changes.
Later studies, especially between 2020 and 2024, strengthened these findings. In trials with older adults and people with Type 2 diabetes, the interval walkers also improved their cholesterol levels, body mass index (BMI), and flexibility, according to The Washington Post.
And it didn't stop there. Researchers also found that participants slept better, had improved cognitive performance, and experienced fewer depressive symptoms.
This makes IWT one of the few routines that offer both physical and mental health benefits something even regular gym-goers don't always get.
Why It Works Better Than Regular Walking
Traditional walking routines often focus on distance or total time like the infamous 10,000 steps. But those benchmarks don't account for intensity.
IWT, in contrast, plays with intensity in a way that pushes the heart, muscles, and lungs just enough, then gives them time to recover. That 'push and pause" approach is what makes interval training so effective — and why athletes, runners, and now even walking researchers use it.
As the article in The Washington Post puts it: 'Participants who tried to walk briskly for 30 minutes straight found it too hard, but when they broke it into three-minute bursts, they were able to sustain it." That's a big win for real-world sustainability.
Getting Started: No Fancy Gear Needed
You don't need a smartwatch, treadmill, or gym membership. Just a pair of comfortable shoes and 30 minutes.
Here's how to begin:
Walk briskly for 3 minutes. You should be breathing hard enough that full conversation is difficult.
Then slow down for 3 minutes. This is your recovery.
Repeat the cycle five times for a total of 30 minutes.
If that feels like too much in the beginning, start with just two or three cycles and work your way up.
You can use landmarks to guide your pace. Walk fast between two street lamps, then slow down until the next one. You can also listen to music that switches tempo, or set a simple timer on your phone.
The ability to recover faster between the fast intervals is a sign your cardiovascular fitness is improving.
Who Is This Good For?
This walking style is especially helpful for:
Middle-aged or older adults trying to stay active without overdoing it
People with Type 2 diabetes, high blood pressure, or early heart issues
Anyone looking for a low-cost, low-impact fitness routine that fits real life
Even younger people who've grown tired of the gym or intense fitness trends are finding value in this method. The structure keeps you engaged without being overwhelming and the benefits stack up over time.

More Effective Than 10,000 Steps?
In many cases, yes. While 10,000 steps is a decent rule of thumb for general movement, IWT delivers measurable cardiovascular and muscular benefits in less time.
The Japanese team behind the method observed health gains in as little as five months, without requiring participants to overhaul their entire lifestyle.
So if you're someone who's been walking endlessly on a treadmill with no change in your blood pressure, stamina, or weight this is your sign to try walking smarter, not longer.
The Japanese method of Interval Walking Training is not a fad. It's a low-effort, high-benefit approach to health that's backed by science, requires no special equipment, and fits into even the busiest schedules.
