Which of the following is considered a low-impact exercise alternative?

Swimming is considered a low-impact exercise because it provides a full-body workout while minimizing stress on the joints. The buoyancy of water supports the body, reducing the impact that occurs with weight-bearing activities. This makes swimming particularly beneficial for individuals with joint pain, arthritis, or those recovering from injury, as it allows for cardiovascular conditioning and muscle strengthening without the risk of injury associated with higher-impact exercises.

In contrast, running, jumping rope, and high-intensity interval training involve significant impact on the joints due to their weight-bearing nature and the repetitive motions required. These activities can place strain on the knees, hips, and ankles, which may be less suitable for individuals seeking a gentler form of exercise.
