ShinshuCore: Japanese Walking

Japanese Walking made simple: 3 minutes fast, 3 minutes slow, 5 rounds. Audio and haptics guide your pace. Free, no account, no subscription.

A structured walk, without watching a stopwatch. ShinshuCore guides you through Interval Walking Training (IWT): 3 minutes of brisk walking, 3 minutes of easy walking, repeated 5 times. One session takes 30 minutes. Sound, haptics, and Live Activity help you follow the intervals while your phone stays in your pocket.

THE SHINSHU METHOD IWT was developed by Dr. Hiroshi Nose and colleagues at Shinshu University in Japan. ShinshuCore follows the 3+3-minute structure and tracks a weekly target of 4 sessions and 60 minutes of brisk walking. Choose a pace that suits you.
