The method
A walk with a rhythm to it
Interval walking training was developed and studied in Japan. Instead of strolling at one steady pace, you alternate three minutes of relaxed walking with three minutes of brisk, purposeful walking — then repeat the cycle. That swing in effort asks more of your heart and legs than a constant pace, without a gym, gear, or running.
Why it works
More from the same half hour
Effort that adds up
Alternating intensity builds aerobic fitness and leg strength more effectively than walking at one steady speed for the same length of time.
Nothing to carry
No treadmill, no wearable required. A pair of shoes and somewhere to walk is the whole setup.
You never watch the clock
Ritmo speaks each switch between slow and fast and tracks the intervals for you, so your attention stays on the walk.
Your effort, recorded
Steps, distance, and every session land in a simple calendar, so progress over the weeks is easy to see.

Common questions
Interval walking, answered
What is Japanese interval walking?
Japanese interval walking — also called interval walking training — is a method developed and studied in Japan in which you alternate three minutes of relaxed, easy walking with three minutes of brisk, purposeful walking, then repeat. The swing in effort asks more of your heart and legs than walking at one steady pace.
How long should an interval walking session be?
About 30 minutes is a common target — five cycles of three minutes slow and three minutes fast. Beginners can start shorter and build up. In Ritmo you can pick anything from 6 to 120 minutes.
Is interval walking better than regular walking?
Alternating intensity builds aerobic fitness and leg strength more effectively than walking at one steady speed for the same length of time, because the brisk intervals lift your effort well above a comfortable stroll.
Is Japanese interval walking the same as brisk walking?
Not quite. Brisk walking is one fast pace held throughout. Japanese interval walking alternates brisk walking with easy recovery walking, so you get the fast effort plus time to recover before the next push.
Do I need any equipment for interval walking?
No. You need shoes and somewhere to walk. Ritmo handles the timing and counts your intervals using your phone — no treadmill or wearable required.
