Japanese ‘interval’ walking offers simple effective exercise

A new fitness trend sweeping social media promises a simple yet effective way to boost health and stamina. Known as Japanese walking, the regimen involves alternating between periods of normal walking and short bursts of faster walking, typically for 30 minutes. Its appeal lies in its accessibility, requiring no gym membership, equipment, or special skills. all that is needed is a pair of comfortable shoes and an open path.

Developed by Japanese researchers more than 20 years ago, Japanese walking was designed to improve physical fitness among middle-aged and older adults while helping prevent lifestyle-related diseases such as obesity and diabetes. Early studies suggested that interval walking could help reduce blood pressure, increase thigh muscle strength, and improve cardiovascular capacity, known as VO2 max, a key indicator of aerobic fitness. Later research found that five months of interval walking could improve participants’ health indicators by 10 per cent to 20 per cent. A 2025 study echoed these findings, reporting measurable improvements in lower-limb strength, aerobic endurance, and resting blood pressure among older adults who followed the regimen consistently.

Medical experts say Japanese walking appeals to those new to exercise because it is manageable and not intimidating. Dr. Sergiu Darabant, a cardiologist at Miami Cardiac & Vascular Institute, part of Baptist Health South Florida, noted that the practice offers a gentle entry point from a sedentary lifestyle while still supporting heart health. Dr. Irvin Sulapas, a sports medicine physician and associate professor at UTHealth Houston, agreed that anyone can benefit from the exercise without resorting to grueling workouts.

In practice, Japanese walking typically alternates three minutes of brisk walking at around 70 per cent of one’s peak aerobic capacity with three minutes at a slower pace of 40 per cent, repeated for at least 30 minutes on four days a week. Experts recommend increasing the frequency to five days per week to meet the American Heart Association’s weekly target of 150 minutes of moderate-intensity exercise. Brisk walking is generally considered about four miles per hour, roughly a 15-minute-per-mile pace, though intensity can vary by individual.

Safety remains a priority. Both physicians advise consulting a doctor before beginning the routine and discontinuing immediately if pain occurs. The workout can also be performed indoors on a treadmill, with a slight incline of one to two per cent to simulate outdoor resistance. Nonetheless, walking outdoors, particularly in natural surroundings, offers additional mental health benefits, including stress reduction, enhanced focus, and a stronger connection with nature.

For those seeking greater intensity, Japanese walking can serve as a foundation for jogging or walking with a weighted vest, further improving outcomes. However, consistency remains key. Experts emphasize that sustainable health gains depend on committing to a long-term exercise routine rather than focusing solely on intensity.

Both Sulapas and Darabant incorporate Japanese walking into their own fitness routines. Sulapas uses it near the end of half-marathons, while Darabant relies on it as a reliable alternative when time or energy is limited. Their experiences reflect the regimen’s adaptability, making it suitable for beginners and seasoned exercisers alike.
