Japanese interval walking, a technique alternating between brisk and slow-paced walking, is gaining traction as a potentially more beneficial alternative to the traditional 10,000-step goal, according to health experts and recent scientific studies.
The method, which went viral after Harvard and Stanford-trained gastroenterologist Dr. Saurabh Sethi shared it with his 1.5 million Instagram followers, involves alternating three minutes of slow walking with three minutes of brisk walking for about 30 minutes daily. In his widely shared video, which has amassed over 2 million views and 54,200 shares, Dr. Sethi claims this approach supports better blood pressure, reduces stroke risk, improves mood, boosts immunity, and enhances sleep quality.
Though labeled as a “Japanese walking method” due to early research conducted in Japan, interval walking applies principles similar to those used in high-intensity interval training (HIIT) and various exercise programs worldwide. The approach isn’t entirely new but has gained renewed interest as more research emerges about its effectiveness.
Scientific evidence suggests interval walking offers measurable health benefits when practiced consistently. A landmark 2007 study comparing no exercise, moderate continuous walking, and high-intensity interval walking found that participants in the interval group experienced up to 17% increase in muscle strength, improved aerobic capacity, and more significant reductions in blood pressure compared to those who walked at a steady pace.
Building on these findings, a 2013 study focusing on individuals with type 2 diabetes revealed even more promising results. Interval walkers showed a 16% increase in VO2max (a measure of aerobic fitness), reductions in body fat, and improvements in blood sugar levels, while the continuous walking group showed minimal changes in glycemic control.
A 2024 review of multiple trials confirmed these benefits, reporting that interval walking can increase aerobic fitness by approximately 10-15%, improve muscle strength, and reduce blood pressure while also positively affecting lifestyle-related disease markers including blood glucose and BMI.
Dr. Tarun Kumar, Associate Director and Head at Medanta Moolchand Heart Centre, explained the physiological advantages: “When you’re walking at different speeds, your heart, muscles and joints work at different thresholds,” making interval walking “superior to steady, constant pace walking” for cardiovascular fitness, muscle strength, metabolic health, and weight management.
Dr. Kumar recommends beginning with a 5-10 minute warm-up followed by cycles of brisk walking at 50-60% of maximum heart rate for 3-4 minutes, alternating with slower walking for about 2 minutes. This pattern should be repeated for 30-40 minutes before cooling down, ideally 4-5 times weekly.
However, experts emphasize that interval walking isn’t universally superior for everyone. Dr. Sanjay Bhat, Senior Consultant in Interventional Cardiology at Aster CMI Hospital, Bengaluru, notes that while interval walking can be more time-efficient than pursuing 10,000 steps, its effectiveness varies based on individual fitness levels, health conditions, and consistency.
“It can be more efficient than just setting a target of 10,000 steps because the bursts of speed improve heart health, blood pressure and overall fitness,” Dr. Bhat said. “It is not necessarily ‘better’ for everyone; total daily activity, fitness level and the ability to maintain the routine also matter.”
The two approaches serve different purposes: interval walking focuses on intensity and time efficiency, while the 10,000-step goal promotes overall daily movement and calorie burn. Dr. Bhat cautions that individuals with cardiovascular disease, uncontrolled hypertension, severe arthritis, or recent surgery should consult healthcare providers before starting an interval walking regimen.
For sedentary individuals, experts stress that any form of movement is beneficial. Those already active may find additional benefits by incorporating interval-style walking into their routine, but the improvements in mood, sleep, and overall health require regular and sustained practice rather than sporadic efforts.
As interest in more efficient exercise methods grows, interval walking represents a structured yet accessible approach to incorporate higher-intensity activity into daily routines, potentially maximizing health benefits without significantly increasing time commitment.

The claim that interval walking can improve mood, immunity, and sleep quality is intriguing. I wonder if the mental health benefits come from the physical activity itself or the variation in pace and intensity.
While the ‘Japanese interval walking’ label may be a bit of a marketing gimmick, the underlying principles seem sound. I’ll have to give this a try and see if it boosts my fitness and well-being.
It’s good to see more research emerging on the effectiveness of interval walking. I imagine this approach could be more sustainable and accessible for many people compared to intense HIIT sessions.
Interesting that interval walking is gaining traction as a potential alternative to the traditional 10,000-step goal. I’m curious to learn more about the specific health benefits it’s shown to provide.
I’m skeptical of any health fad that goes viral on social media, but the scientific evidence on the benefits of interval walking does seem promising. I’d be curious to see longer-term studies on its impacts.
This ‘Japanese interval walking’ method sounds like a smart way to incorporate HIIT principles into a walking routine. I wonder how the results compare to dedicated HIIT workouts in terms of cardiovascular and metabolic benefits.
As someone who struggles to meet the 10,000-step goal, I’m intrigued by this interval walking technique. The idea of alternating brisk and slow pacing sounds manageable and potentially more engaging than just steady-state walking.
