Interval walking means fast and slow walking together. First, walk slowly and feel warm. Then walk fast for one minute. Your heart works more, and you breathe faster. You can talk, but singing is hard. Next, walk slowly for the same time. This gives your body a short rest. Then do it again. Fast walking is useful exercise. Short walks count too. (cdc.gov)
For example, walk to a small shop. Walk fast to the next corner. Walk slowly after the corner. Change your speed on the way. Wear good shoes and choose a safe road. Start slowly if this is new. Stop if you feel pain or feel sick. This simple change can make walking more fun.
