What is the Japanese Interval Walking Method?
The Japanese interval walking method (IWT) is a walking protocol developed by researchers at Shinshu University, Japan. It alternates periods of brisk, faster-paced walking with periods of slower, easier walking. The standard version uses three minutes of fast walking followed by three minutes of slow walking, repeated five times for a 30-minute workout. Studies have suggested it may improve cardiovascular fitness and lower blood pressure more effectively than continuous moderate-intensity walking.
This timer handles all the counting so you can focus entirely on your pace. Set your preferred fast and slow durations and number of sets, press Start, and follow the audio cues as you walk. See the FAQ for common questions, or read more about how it works.
