3-3-30 Walk: A 30-Minute HIIT-Inspired Health Boost
Good Housekeeping promotes daily 30-minute brisk walks and a 3-3-30 interval method (three minutes fast, three minutes moderate, repeated for 30 minutes) as an HIIT-like boost to cardiovascular and mental health, citing Shinshu University research that the alternating pattern produced the greatest improvements and dementia/osteoarthritis protection. The magazine also launches a 5 Million Steps Challenge to accumulate a collective total of 5 million steps, recommends adding weights for extra intensity, and highlights the Fit (Enough) Club for ongoing motivation.
