A walking style from Japan is becoming popular around the world. People often share it on social media. It is called interval walking. An interval means changing between two different speeds. (brownhealth.org)
First, walk fast for three minutes. Then, walk slowly for three minutes. Keep changing the speed during your walk. The fast part should feel quite hard. However, you do not need to run. Researchers tested this method with middle-aged and older adults. Studies found better fitness and lower blood pressure. The fast walking part seems especially important. (pubmed.ncbi.nlm.nih.gov)
For example, a busy worker walks after dinner. She uses a phone timer and chooses a flat road. During the fast part, she walks like she is late. Her breathing becomes stronger, but she does not run. When the timer rings, she slows down and relaxes. She repeats this pattern until she reaches home. The changing speed makes her usual walk feel like a game.
This method needs no gym or special machine. Comfortable shoes and a safe road are enough. Begin gently if exercise is new for you. People with health problems should ask a doctor first. (brownhealth.org)
