Walking can feel boring when every step has the same speed. A Japanese method makes it more like a simple game. (shinshu-u.ac.jp)
It is called interval walking. An interval is a change between two kinds of activity. Walk fast for three minutes, then slowly for the same time. Repeat this pattern several times. During the fast part, breathe harder, but do not run. During the slow part, relax and prepare for the next fast part.
Research has tested this method with middle-aged and older adults. Regular practice can improve fitness and make leg muscles stronger. Fitness means how well your body can work. Recent studies also suggest better movement in some people. However, results can be different for each person. (jstage.jst.go.jp)
For example, Aya walks after dinner. She starts a timer and walks quickly. When it rings, she slows down. She keeps changing her speed until she reaches home. At first, the fast part feels difficult. After some weeks, the same road feels easier.
This method needs no gym or special sports clothes. The slow part gives your body a short rest. So, an everyday walk can become useful training. If you feel pain or dizziness, stop and rest.
