A new fitness trend taking over social media is “Japanese walking,” a simple yet effective 30-minute workout that alternates between normal-paced walking and short bursts of faster steps. Its appeal is clear: no gym membership, no special equipment, just step outside and start moving.
Dr. Irvin Sulapas, a sports medicine physician at UTHealth Houston, says anyone can do it. “You don’t need to do super high-intensity workouts where you’re sore and exhausted to improve your health,” he explains.
Originally developed in Japan over 20 years ago, the method was designed to boost physical fitness among middle-aged and older adults and prevent lifestyle-related conditions such as diabetes and obesity. Studies have shown high-intensity interval walking can lower blood pressure, strengthen thigh muscles, and improve cardiovascular endurance. Research published in 2009 even found five months of interval walking improved participants’ health markers by 10% to 20%.
A more recent 2025 study confirmed these benefits, showing that older adults practicing Japanese walking for five months saw improvements in resting blood pressure, lower-limb strength, and VO2 max—a key measure of aerobic fitness.
Dr. Sergiu Darabant, a cardiologist at Miami Cardiac & Vascular Institute, points out that Japanese walking is especially appealing because it offers a gentle entry point for those new to exercise. “It’s not intimidating,” he says.
Getting started is straightforward. The classic approach involves alternating three minutes of brisk walking at about 70% of your peak aerobic capacity with three minutes at a slower pace of 40%, for at least 30 minutes, four to five days a week. Experts suggest walking as fast as you can without breaking into a jog, roughly four miles per hour for most people.
Safety is key. Check with your doctor before beginning any new exercise and stop if you experience pain. If outdoor conditions aren’t ideal, you can do Japanese walking on a treadmill with a 1% to 2% incline to simulate outdoor resistance. But both Sulapas and Darabant agree that walking in nature adds extra benefits, from reducing anxiety to boosting mental engagement.
Once comfortable with Japanese walking, you can gradually increase intensity by jogging or using a weighted vest. The most important part, according to Darabant, is consistency. “Exercise is a marathon, not a sprint,” he says. “A gradual, consistent approach leads to lasting lifestyle changes.”
Both physicians incorporate Japanese walking into their routines. Sulapas uses it toward the end of his half-marathons, while Darabant turns to it when time or energy is limited. “It’s always my go-to backup,” he says.
Japanese walking may be simple, but its health benefits—from heart and muscle strength to mental well-being—make it a trend worth trying.
