One of the most surprising fitness stories of 2026 is not a new machine or a hard gym challenge. It is a walking method from Japan. In PureGym’s 2025/26 UK Fitness Report, “Japanese walking” was named the fastest-growing fitness trend for 2026. The report says search interest rose by 2,968%, based on Google search data comparing July-September 2024 with the same months in 2025. PureGym also says this boom matches a wider move toward low-impact, easy-to-start exercise. (puregym.com)

The method itself is much older than the trend. It comes from Interval Walking Training, developed by researchers at Shinshu University in Japan. The basic pattern is simple: walk fast for three minutes, then walk more slowly for three minutes, and repeat. Shinshu University explains that the faster part should be at 70% or more of your peak aerobic capacity, while the easier part is around 40%. In another research summary, participants were told to do five or more of these cycles on four or more days each week. (shinshu-u.ac.jp)

Why has it become so popular? Because it sounds simple, but it is supported by real research. A 2007 study in Mayo Clinic Proceedings followed 246 middle-aged and older adults for five months. The interval-walking group showed better improvements in physical fitness and blood pressure than the group doing moderate continuous walking. A later PubMed-listed study in middle-aged adults also reported that short periods of harder walking mixed with easier walking could increase aerobic capacity and reduce resting systolic blood pressure.

The global boom seems to have been pushed by online videos and major media coverage. PureGym calls it a viral TikTok trend, and on July 31, 2025, the New York Times’ Well section featured it. UCSF later described “Japanese walking” as an accessible, research-backed way to improve cardiovascular health, leg strength, and overall fitness. That is probably the real reason for its success in 2026: it is cheap, practical, and easy to try, but it still feels smart and modern. (puregym.com)
