WALKY makes "Interval Walking Training (IWT)" — the method developed by a Shinshu University research team in Japan — easy, cute, and effortless. Just alternate "3 minutes slow → 3 minutes fast," and the same amount of walking builds far more strength and cardio.

■ Why Interval Walking (IWT)? In a 5-month study, leg strength rose +13–17%, peak aerobic capacity +8–14%, with improved blood pressure. The goal: 60 minutes of fast walking a week (4 days is plenty). Short, hard, and effective.
