大阪长者水中健走，轻松锻炼身心，广受欢迎
In a warm pool in Osaka, Japan, a group of older people walks slowly. The water is only waist-deep. They smile and talk as they move. This is a water walking club. It meets two times a week at a public pool.
Water walking is simple exercise. You walk in the pool. You do not need to swim. The water holds part of your body weight. This makes walking feel very easy. It is gentle on your knees and back. Older people love it because it does not hurt.
