The newest walking trend is almost twenty years old.
“Japanese walking” is all over short-form video this year: three minutes of fast walking, three minutes of easy walking, five times through. It needs no gym and no equipment, and it fits into half an hour. Behind the clips is a method from a university lab in Japan that has been studied since 2007, and one finding from that research gets far less attention than the routine itself.
What Japanese walking is
The method is called interval walking training. It was developed by exercise physiologists Hiroshi Nose and Shizue Masuki at Shinshu University in Matsumoto, Japan. A session alternates two paces:
- Three minutes fast. A brisk pace where talking takes effort. In the research it was set above 70% of each person’s peak aerobic capacity for walking.
- Three minutes easy. A relaxed pace, around 40% of that capacity, to recover.
- Five rounds or more, about 30 minutes, on four or more days a week.
The speeds are personal. One person’s fast walk is another person’s easy one, which is part of why the method suits so many people: beginners, older adults, and lifters who want something gentler on the days between heavy sessions.
Why it’s trending now
PureGym’s annual UK fitness report named Japanese walking the fastest-growing fitness search it tracked, with Google searches up nearly 3,000% from July to September 2025 compared with the same months of 2024, as Athletech News reported. Much of that came from social video. Search interest is a measure of curiosity, not of results, but the appeal is easy to see: it is walking, made a little more structured.
What the research found
The study most clips refer to is Nemoto and colleagues, published in Mayo Clinic Proceedings in 2007. Over five months, 246 adults with an average age of 63 were split into three groups: no walking program, moderate continuous walking (8,000 steps or more a day, four or more days a week), and interval walking.
- In the interval group, knee extension strength rose 13%, knee flexion strength 17% and peak aerobic capacity for walking 9%.
- Those gains were significantly larger than in the continuous walking group.
- Resting systolic blood pressure fell more in the interval group too.
Some honest limits: these were middle-aged and older adults, the program lasted five months, and the outcomes were fitness measures rather than long-term health events. Many of the follow-up studies come from the same research group. It is a promising, well-studied way to walk, not a guarantee.
The finding the videos skip
Read the results closely and one line stands out. In the interval walking group, 11 of 19 men and 31 of 68 women met their training targets. That is fewer than half of the group. The routine is easy to explain and easy to start, and still hard to keep doing four days a week for five months.
That matches what I have seen in my own training. The plan is rarely the problem. Showing up again on a rainy Tuesday is. In the study, accelerometers counted every interval for the participants; outside a lab, nobody counts them for you unless you write them down.
How to try a session
- Walk easily for a few minutes to warm up.
- Walk fast for three minutes: arms swinging, breathing harder, talking possible but not comfortable.
- Walk easily for three minutes and let your breathing settle.
- Repeat the fast and easy pair until you have done five rounds, about 30 minutes.
- Finish with a few easy minutes, then log the walk.
A phone timer is enough to keep the intervals. On a treadmill, a little incline can make the fast minutes harder without walking faster. If five rounds is too much at first, start with two or three and add a round when it feels manageable.
Log each walk so you keep going
In One Fitness Hub, a walk is a cardio entry. Open the Log, pick Outdoor - Walking (or Indoor - Walking for a treadmill) and enter the total time and distance. Pace, speed, Cardio Score and estimated calories fill in as you type, and an Incline % adjusts the estimate for treadmill walks.
One honest limit: the app records the walk as one entry with its total time and distance, not each three-minute interval, and it does not read data from a watch. To keep the structure, tap Notes and add a line such as “5 rounds, 3 fast and 3 easy, windy.” Ten seconds now explains the number months later.
Over a few weeks the log turns into something useful:
- Your pace on the same route. If the same 30 minutes covers a little more distance, your fast minutes are getting faster.
- Your weekly walking distance, charted apart from running in My Performance, Cardio.
- Your walking days on the Yearly View calendar, so four days a week is something you can see, not something you remember.
- Your food. If you choose to add the workouts you log in Nutrition, a walk’s estimated active calories go into that day’s budget.
Where One Fitness Hub helps
- Log every walk, run and lift: time and distance for cardio, sets and reps for strength, with the Help Center guide to get started.
- See your consistency: a calendar of every session, so the four-days-a-week goal is visible.
- See the trends: weekly cardio distance and pace over weeks, not just today.
- Track nutrition and your body beside your walking, so one record holds the whole picture.
Three minutes fast, three minutes easy. Write it down, and do it again on Thursday.

Pace, Cardio Score and calorie figures in the app are estimates, not medical measurements, and the study results describe groups of people, not what will happen for you. Check with your doctor before you start or change an exercise program, especially if you have a heart, blood pressure or joint condition.
