Yes. Over 5,000 participants in Shinshu University studies showed meaningful improvements in cardiovascular fitness, blood pressure, and leg strength — consistently better than steady-pace walking over the same duration.
Regular walking is one speed. Interval walking alternates between fast and slow periods — 3 minutes each. The variation forces your body to adapt in ways steady effort doesn’t — similar to why HIIT training outperforms steady cardio.
Walk briskly for 3 minutes, then walk at a relaxed pace for 3 minutes. Repeat for 30 minutes total. DJ Walk handles the timing through your music so you don’t need to track it manually.
It depends on your natural stride. Your ideal pace is personal — that’s why DJ Walk calibrates to your actual walking speed and matches songs accordingly.
The app uses your Apple Music library to build personalized interval playlists. If you don’t have Apple Music, you can use the app as a timer-only tool.
