Swimming is perfect for the elderly because it’s easier on the joints and muscles than exercise on hard land. This is good news for those with chronic diseases, such as rheumatoid arthritis and osteoporosis, which is a decrease in bone density as a person ages.

Swimming also boosts flexibility, especially in the neck, legs, arms and hips, leading to reduced back pain and sore muscles, as well as better posture and muscle coordination
