Japanese walking: a practical guide to walking intervals

What changes when you walk in intervals

You can use your usual route and keep walking throughout. After an easy stretch, pick up the pace for a set time, then slow down again. The easier sections let your breathing settle before the next brisk stretch.

Choose a fairly level route with few road crossings at first. Comfortable shoes and a watch or timer are enough. Let your arms swing naturally and take quicker steps without reaching far ahead with your feet.

Choose your first session

If you have not walked much lately, start with the short option. It is an easier practice session, rather than the full research protocol. If longer walks already feel comfortable, you can build towards the longer pattern.

Begin either option with about three minutes of easy walking and finish with another two easy minutes. Add these five minutes to the times in the table: roughly 14 minutes for the starter or 35 minutes for the longer session.

In the web timer, choose intervals and the walking preset for the 3+3 pattern. For the starter, enter 120 seconds for easy walking, 60 seconds for brisk walking and three rounds. Walk easily for three minutes before starting the timer. When it finishes after nine or 30 minutes, walk easily for another two minutes. Keep the browser page visible and the screen on so you can follow the changes reliably.

How fast is brisk?

For your first sessions, walk quickly enough to breathe more deeply while still being able to talk. Singing would be difficult. The easy section should feel noticeably lighter. You do not need a fixed speed or a heart-rate zone on your watch.

If you are gasping after a few steps, slow down. When walking with someone, choose a pace that suits the person finding it harder. Heat and hills also make the same route more demanding.

Turn it into a regular walk

Two convenient days make a simple start, such as Tuesday after work and Saturday before breakfast. Repeat the same session first. When it feels comfortable during and afterwards, extend the brisk sections from one minute to two, then three. Or add another round. Change one thing at a time.

An easy stroll can be enough after a demanding leg workout. Keep a familiar short route for busy weeks. Missing a walk does not mean you need to make the next one especially hard.

Where the three-minute pattern comes from

In a Japanese study published in 2007, adults averaging 63 years old trained for five months. The interval programme called for at least five cycles of three easy minutes and three fast minutes on at least four days a week. Fast walking intensity was set relative to each participant’s fitness.

The interval group improved outcomes including aerobic fitness. The longer option above follows the same 3+3 timing. The talking pace described here is a moderate starting point and does not reproduce the individually measured intensity used in the trial. The short starter session was not tested in that study.

If the session feels too hard

Shorten the brisk sections or stroll for the rest of the walk if you cannot comfortably maintain the pace. Stop and seek medical help for chest pain, dizziness or unusual breathlessness. If a medical condition limits your activity, discuss harder intervals with your treating clinician first.

Make room for your next walk

A LiftPal Daily Goal can be as simple as “Go for an interval walk on Tuesday”. Tick it off when you get back. If you use Apple Health for steps, you can also include the extra movement in your step goals.

If you would rather begin by walking more overall, use the step-goal calculator to choose a manageable next target. The return-to-movement guide offers more short options for getting started again.
