Japanese slow jogging is jogging slowly enough to smile, talk or sing while moving. That smiling pace, called niko-niko pace, turns jogging into gentle aerobic exercise for older adults. Exercise physiologist Hiroaki Tanaka of Fukuoka University developed the method around that effort test. According to The Conversation, the pace stays conversational by design The Conversation report.

What does smiling pace feel like?
Pick speed by face and breath, not by the watch. If you can smile and speak in full sentences, you are in range. If speech breaks apart, slow down until it returns.
For many older beginners, that effort lands near walking speed. The test travels well because fitness differs. A trained runner may feel little strain where an inactive adult feels real work.
How is the stride different?
Running State describes short steps, relaxed posture, midfoot or forefoot landing, and a quick cadence near 180 steps per minute Running State guide. For older or beginning joggers, the pace can be as slow as 2–3 mph.
Think quiet feet and tall hips. Keep steps short, land softly under the body, and let the arms swing loosely. The goal is lift-off on each step without pushing or bouncing.
What did older adults gain?
A randomized trial studied 81 independent community-dwelling adults averaging 70.8 years. They alternated 1 minute of slow jogging at walking speed with 1 minute of walking for 12 weeks.
A Springer Medicine summary reports the program was easily performed, including by adults with low muscle mass Springer Medicine summary. It improved aerobic capacity, leg muscle function, and muscle composition, including less fat infiltration.
How can it fit your week?
WHO guidance recommends 150–300 minutes of moderate aerobic activity weekly, while noting some activity beats none WHO guidance. Slow jogging helps because its relative intensity lets inactive or older beginners count gentle jogging toward that total.
Track minutes across the week rather than chasing distance. A calm 20-minute jog-walk counts more than a hard five-minute push.
- Start with 10–15 minutes total, alternating 1 minute of easy jogging with 1 minute of walking.
- Keep the face relaxed and speech easy through each jog minute.
- Add a few minutes per session until weekly minutes climb.
Where are the limits?
Reviewers cited by The Conversation note little research tests "slow jogging" by name. Intensity is also relative to the person doing it.
So a pace that feels trivial to a trained runner may feel moderately hard to an inactive older adult. Treat a first week that feels almost too easy as correct dosing, not failure.
